Short description: |
The course will acknowledge the students with the basic problems of a modern biochemistry, the knowledge of which shall allow understanding of tasks and challenges of medicine and pharmacology of the 21st century. Basic components and processes of cell metabolism, with consideration of enzymatic transformations, gene expression and energetic processes will be discussed. |

Learning outcomes: |
After finishing this course the student: knows the outline of a living cell structure and its basic organelles (cell nucleus, mitochondrion, chloroplasts, extracellular walls and membranes, intracellular membranes). He knows the chemical and physicochemical characteristics of the basic structural compounds of the cell: proteins, carbohydrates, nucleic acids, lipids. He understands the metabolic role of enzymes, hormones, deoxy-and rybonucleic acids, co-enzymes, sugars and mineral components of the cell. He knows the functions and the role of the main pathways, metabolic cycles and cellular processes (replication, transcription, translation, glycolysis, fermentation, Krebs cycle, pentose phosphate cycle, gluconeogenesis, beta-oxidation of fatty acids, biosynthesis of fats, urea cycle). He understands the physical (thermodynamical and electron) basis of the processes of energy transformation in living cells, in the electron transport chain and during photosynthesis. |
Assessment methods and assessment criteria: |
Passing of two written tests during a semester is required. Obtaining positive grades may be a reason for an exam dispensation. Exam in a written form, in doubtful cases also in oral form. |
