Schedule of laboratory lessons and seminars
Requirements for acknowledgement of the semester
- Participation in the laboratory practicals, consultations and seminars is obligatory; students have to sign the attendance sheets at the end of every lesson. In case of more than three absences from the practical lessons for any reason, the semester will not be acknowledged and the student is not allowed to sit for the semifinal exam. Missed practicals can be completed only in the same week at another group; certificate from the host teacher should be presented by the student to his/her own teacher. The schedule of practical lessons, consultations and seminars can be downloaded from the official homepage of the Institute.
- Both midterm examinations have to be passed before the commencement of the examination period
Midterm examinations
Two midterm examinations will be held in the weeks 6 and 10 of the semester, respectively (Oct. 13, 2016 17:30; Nov 10, 2016 17:30). For details visit our homepage: https://semmelweis.hu/biokemia/en/
25 multiple choice type questions and 2 biochemistry problem sets (panels) are asked. Students may obtain 1 score for each correctly solved multiple choice questions. The both problem sets are evaluated by your own laboratory teachers (points: 0, 2, 3, 4, 5). We calculate the sum of your scores and points of your midterm examination and the tests are graded by the proposed limits of the table below:
Proposed limits for the marks of midterm are:
| Sum of the points and scores | Grade of the midterm examination |
| 0-18 | 1 (fail) |
| 19-22 | 2 (pass) |
| 23-26 | 3 (satisfactory) |
| 27-30 | 4 (good) |
| 31-35 | 5 (excellent) |
The grade for the midterm exam is 1 (fail): (i) if the sum of the scores and the grades is 18, or less (ii) each of the problems are evaluated by 0. Passing both midterms is a prerequisite to acknowledgement of the semester.
Failed midterms might be retaken twice.
The first retakes should be performed on the 20th of October 2016 (retake of midterm I) and on 17th of Nov (retake of midterm II) (for details please, click the homepage of Department of Medical Biochemistry). Students having failed the first retake(s) might sit for the second retake (Dec 1, 2016; 17:30). The second retake is an oral exam conducted by an examination committee. Students having failed the first retakes of both midterms I and II will be examined in the material of both midterms at the same time.
Grading of the performance of the laboratory work
Laboratory work performance assessment is a part of the semi-final exam. The practical work and its documentation is assessed by the laboratory teachers. (0 or 1 point). Maximal number of the collected points for laboratory work in this semester is 8 and these points are equivalent with 3 ‘lab-bonus’ points for the semi-final examination.
| 7-8 points for laboratory work | = | 3 ‘lab-bonus’ points |
| 5-6 points for laboratory work | = | 2 ‘lab-bonus’ points |
| 4 points for laboratry work | = | 1 ‘lab-bonus’ points |
Semi-final exemination
The grade of the semi-final examination is based on four elements:
- theoretical written test of biochemistry problem set and multiple choice type tests (T)
- laboratory examination (L)
- grades of midterm examinations (M)
- ‘bonus points‘ collected in the course of the semester (B) (see also ‘grading of the performance of the laboratory work’)
Theoretical written test (T)
The biochemistry problem sets and multiple choice type test questions are based on the recommended textbook, the lectures and the seminars. The theoretical written test is divided in three blocks (i) block#A set of biochemistry problems (containing questions for 30 points) (ii) block#B 30 multiple choice type test questions (carbohydrates, metabolic integration) (iii) block#C 30 multiple choice type test questions (lipids, amino acids, nucleotides, porphyrins). Correct answer for a biochemistry problems may result in max 1-3 points. The correct solution for a multiple choice type question results in 1 point. Futher points are added to the scores of block#B and block#C on the basis of the midterm examinations (M) of the fall semester of the 2016/2017 academic year.1 Students may pass the semi-final examination with minimal scores of 15, 15, 15 for the block#A, block#B and block#C, respectively. 2 minutes is given for the solutions of each multiple choice type test questions and 30 minutes for the set of biochemistry problems.
Laboratory examination (L)
The laboratory examination is an obligatory part of the semi-final examination. Students get one question based on the attached „list of laboratory questions” and answer it in written form (in 15 Min). These tests are graded by 0, 1, 2 points. Students can not pass the semi-final examination with 0 point from the practical exam. Department of Medical Biochemistry gives the students a chance to write their laboratory test on the last week of the semester (14th week; last week laboratory exam). These tests are graded by 1 or 2 points; unsuccessful tests are only marked as ‘not accepted’.
Results of the midterm examinations (M)
Grades of the 1st midterm examinations as points are added to the scores of block#B, the grades of 2nd midterm examination as points are added to the block#C.
Bonus points collected in the course of the semester (B)
Maximal number of ‘bonus points’ for the fall semester is 7. These bonus points can be collected in the course of fall semester according to the following scheme:
from the grading of the experimental work (‘lab-bonus’ points) (see ‘grading of the performance of the laboratory work’)
- 3 ‘lab-bonus’ points, if the sum of the collected experimental points is 7 or 8
- 2 ‘lab-bonus’ points, if the sum of the collected experimental points is 5 or 6
- 1 point, if the sum of the collected experimental points is at least 4
from oral presentations on the seminars (‘presentation-bonus’ point) accompanied by powerpoint presentations or written summaries in electronic format 4 points, (if the student understands the content of the presented paper, emphasizes the biochemical interrelations and interprets the presented article at the expected level of knowledge)
Grades of the semi-final examination
Total scores from the 4 elements of the semi-final examination = T + L + M + B
| T + L + M + B | Grade |
| if any of block#A, block#B or block#C contains 14 scores or less; if the laboratory examination is graded by 0; if the sum of T+L+M+B 55 or less | Fail (1) |
| 56-69 | Pass (2) |
| 70-82 | Satisfactory (3) |
| 83-95 | Good (4) |
| 96-109 | Excellent (5) |
Students who pass block#A#B#C and the sum of T+L+M+B is 55 or more, but fail on the practical essay have to retake only the practical essay when they repeat the semifinal exam; students who pass the laboratory examination but fail on the written test, have to retake the blocks#A#B#C. Those who want better grade are entitled to rewrite also the block#A#B#C, however, with the risk of performing worse.
‘1 point rule’ if any of the blocks contains 14 point and the other two blocks contain 15 points or more (T) + the laboratory exam is evaluated by either 1 or 2 points (L), the grade for final-examination is 2 (pass) if the sum of scores and points (T+L+M+B) are 59 points or higher.

Semi-final examination
Semi-final exemination
Contact your tutor! Registration for office hours
The grade of the semi-final examination is based on four elements:
- theoretical written test of biochemistry problem set and multiple choice type tests (T)
- laboratory examination (L)
- grades of midterm examinations (M)
- ‘bonus points‘ collected in the course of the semester (B) (see also ‘grading of the performance of the laboratory work’)
Theoretical written test (T)
The biochemistry problem sets and multiple choice type test questions are based on the recommended textbook, the lectures and the seminars. The theoretical written test is divided in three blocks (i) block#A set of biochemistry problems (containing questions for 30 points) (ii) block#B 30 multiple choice type test questions (carbohydrates, metabolic integration) (iii) block#C 30 multiple choice type test questions (lipids, amino acids, nucleotides, porphyrins). Correct answer for a biochemistry problems may result in max 1-3 points. The correct solution for a multiple choice type question results in 1 point. Futher points are added to the scores of block#B and block#C on the basis of the midterm examinations (M) of the fall semester of the 2016/2017 academic year.1 Students may pass the semi-final examination with minimal scores of 15, 15, 15 for the block#A, block#B and block#C, respectively. 2 minutes is given for the solutions of each multiple choice type test questions and 30 minutes for the set of biochemistry problems.
Laboratory examination (L)
The laboratory examination is an obligatory part of the semi-final examination. Students get one question based on the attached „list of laboratory questions” and answer it in written form (in 15 Min). These tests are graded by 0, 1, 2 points. Students can not pass the semi-final examination with 0 point from the practical exam. Department of Medical Biochemistry gives the students a chance to write their laboratory test on the last week of the semester (14th week; last week laboratory exam). These tests are graded by 1 or 2 points; unsuccessful tests are only marked as ‘not accepted’.
Results of the midterm examinations (M)
Grades of the 1st midterm examinations as points are added to the scores of block#B, the grades of 2nd midterm examination as points are added to the block#C.
Bonus points collected in the course of the semester (B)
Maximal number of ‘bonus points’ for the fall semester is 7. These bonus points can be collected in the course of fall semester according to the following scheme:
from the grading of the experimental work (‘lab-bonus’ points) (see ‘grading of the performance of the laboratory work’)
- 3 ‘lab-bonus’ points, if the sum of the collected experimental points is 7 or 8
- 2 ‘lab-bonus’ points, if the sum of the collected experimental points is 5 or 6
- 1 point, if the sum of the collected experimental points is at least 4
from oral presentations on the seminars (‘presentation-bonus’ point) accompanied by powerpoint presentations or written summaries in electronic format 4 points, (if the student understands the content of the presented paper, emphasizes the biochemical interrelations and interprets the presented article at the expected level of knowledge)
Grades of the semi-final examination
Total scores from the 4 elements of the semi-final examination = T + L + M + B
| T + L + M + B | Grade |
| if any of block#A, block#B or block#C contains 14 scores or less; if the laboratory examination is graded by 0; if the sum of T+L+M+B 55 or less | Fail (1) |
| 56-69 | Pass (2) |
| 70-82 | Satisfactory (3) |
| 83-95 | Good (4) |
| 96-109 | Excellent (5) |
Students who pass block#A#B#C and the sum of T+L+M+B is 55 or more, but fail on the practical essay have to retake only the practical essay when they repeat the semifinal exam; students who pass the laboratory examination but fail on the written test, have to retake the blocks#A#B#C. Those who want better grade are entitled to rewrite also the block#A#B#C, however, with the risk of performing worse.
‘1 point rule’ if any of the blocks contains 14 point and the other two blocks contain 15 points or more (T) + the laboratory exam is evaluated by either 1 or 2 points (L), the grade for final-examination is 2 (pass) if the sum of scores and points (T+L+M+B) are 59 points or higher.
1Results of midterm examinations, laboratory exams of earlier studies are not accepted.
Subject matter
Subject title: Medical biochemistry, molecular and cell biology II. (Medicine) Biochemistry, molecular and cell biology II. (Dentistry)
Code: AOOBIBKM_2A (Medicine) FOKOOBI159_2A (Dentistry)
Credit: 6 (Medicine) 5 (Dentistry)

Description of the subject: The objective of the course is to introduce complex molecular interpretation of selected physiological processes in the human organism.
Main topics of the lectures: The subject addresses the metabolic processes in the human organism at molecular level with special emphasis on their medical aspects. The main topic is the metabolism of carbohydrates, lipids, amino acids and nucleotides and its regulation under normal and pathological conditions. Lectures cover the following topics:
- Metabolism of compounds providing energy for the cell function.
- Storage and mobilization of carbohydrates and lipids.
- Gluconeogenesis and biosynthesis of sugar derivatives.
- Biosynthesis of fatty acids, triacylglycerols, cholesterol, bile acids. Biochemistry of the steroidal hormones and the essentioal fatty acids.
- Turn-over of proteins in the human organism.
- Degradation of amino acids and metabolic fate of their carbon atoms.
- Formation and elimination of ammonia. – Biosynthesis of non-essential amino acids.
- Biosynthesis and degradation of nucleotides and heme.
- Integration of metabolic pathways at the level of the whole body (specific metabolic properties of separate organs, metabolic communication between organs).
Students perform laboratory experiments that help them to acquire skills in basic biochemistry techniques. Clinical biochemistry procedures and basic molecular biology techniques are practiced by the students in laboratory experiments. Problem-oriented discussions in seminars serves to introduce edge-cutting research topics of medicine (gene therapy, molecular basis of diseases with high public health impact).
