Seminar reports

Seminar reports

During seminar time through weeks 3-12, – 10 times in total – students will have to report on the lecture and practical topics of the previous twoo week. The 6 test questions containing written test may result in 0-6 points. Evaluation of semester performance will be based on these reports. Failed or missed reports cannot be made up for.

A three-scaled evaluation of semester performance will be based on these reports:

0-49 % Unsatisfactory
50-74 % Satisfactory
75 -> % Excellent

Students having failed to meet the requirements by week 12 may sit for a written or oral exam during weeks 13-14 (Date, time, location are published later).

Acknowledgement of the semester

  • Three or less absences in spring semester.
  • The total score of the weekly reports has to reach at least 50 % of the maximum total score.
  • Acknowledgement (and evaluation) of the semester can be obtained by successful completion of the weekly reports. Alternatively, an opportunity for a written exam on the material of weeks 1-12 will be given during week 13. In case of failure at the written exam students will be given a final opportunity to obtain a “pass” score at an oral exam during week 14. Grading Weekly reports during seminars will be held continuously.

Failure to appear at the written or oral exam must be justified within three business days by submission of appropriate documents.

Course-outline of Medical Biochemistry 1

Spring semester of 2018/2019 academical year

  • Name of the course: Medical Biochemistry 1
  • Credits: 3
  • Neptun code: ÁOKOBI463_1A
  • Lectures:Seminars:1.5
  • Director of the course: Prof. Tretter, László MD, PhD, DSc
  • Course-coordinator: Léránt, István PhD +36-20-6632267
  • Student affairs office: EOK-Building, Room 1.508
  • Student affairs secretary: Mrs. Pichler Vera   +36-1-4591500#60061; 

The aim of the curriculum is to learn and understand the structure-funcion aspects of biologically important macromolecules (proteins, nucleic acids, lipids and complex carbohydrates) and that of their their building blocks (amino acids, nucleotides, sugars and lipids). The enzymology modul deals with the mechanism and efficiency of the in vivo biochemical reactions focusing on their organization into metabolic pathways, their regulation and effectivity. The bioenergetics modul focuses on the energy and metabolite fluxes of the human body and also settle the basis of the thermodinamycal approach of intermedier metabolism.
