Midterm 1

Midterm 2

Topic list



The principal aim of the course is to provide an insight into the structure and function of biologically important molecules including amino acids, carbohydrates, lipids, vitamins, coenzymes (descriptive biochemistry), as well as proteins, enzymes and nucleic acids. This module is a prerequisite to the understanding of the intermediary metabolism of the cell. The cell biology unit describes the principles of organization of cells as well as the function of subcellular organelles. The molecular biology module aims at highlighting the storage and expression of genetic information throughout replication, transcription and translation as well as our current understanding of the regulation of gene expression, followed by an up-to-date summary of currently used methods in molecular biotechnology.


  1. Exemption may be given only if students pass an exemption examination
  2. Prerequisite of participating in the exemption exam: previous studies and successful examinations in the subject Biochemistry (final exam) (Biochemistry I, II, III)
  3. Documents to be attached on the previous studies:

a transcript from the former University, containing the name of courses taken in Biochemistry, examination grades and a copy of your final BSc or MSc diploma (if you have)

a topic list of Biochemistry (bioenergetic, metabolism of carbohydrates, lipids, amino acids, nucleotides, biochemistry of tissues, neurobiochemistry, signal transduction, haemostasis and/or molecular biology (macromolecules) (for final exam) (Only official hardcopy version of documentation is accepted, we do not accept e-documentation).

the indication of the used textbook(s) is also recommended

will be organized by our examination committee.

  1. Oral examinations in Biochemistry
  1. The exemption examinations take place on the 5th or 6th week of the semester (Febr 29-04 or March 7-11, 2016); the deadline to present your documents is the end of the 2nd week (February 12, 2016).
  2. In case of unsuccessful exemption examination there are not any negative consequences. You have to attend laboratory lessons and seminars throughout the semester and sit for the regular examination at the end of the semester like the rest of students.
