Syllabus
  • 1. Four principles of structural and functional organization of a cell: (a) chromosomes and ribosomnes; (b) membranes; (c) cytoskeleton; (4) cell envelope. 2. Components of cell membranes, their hierarchical organization. Lipids and proteins, sugar components. Movement of membrane components. Physico-chemical basis of interac-tions within membranes and between membranes. 3. Synthesis and composition of membrane lipids and proteins, their movement to their destination in the cell. 4. Three categories of membrane functions: flow of matter, flow of energy and flow of information. 5. Physico-chemical principles of movement across membranes, its kinetics and ener-getics. 6. Nonspecific permeation of substances. Dissolving in lipids and movement through permanent and transient pores. 7. Theory of specific transport. Examples of movement through channels, on trans-porters and by group translocation. Endocytosis and exocytosis. 8. Conversions of energy in membranes. Physical reactions of photosynthesis. Struc-ture of chloroplasts, light-harvesting complexes, photosynthetic reaction centres. 9. Structure and function of mitochondria. Formation of gradient of electrical potential and of pH. Synthesis of ATP. 10. Conversions of mechanical and electrical energy. 11. Flow of information signals across membranes. Molecular basis of their trans-duction. 12. Physical signals and their processing vision, hearing, touch, perception of temperature, of magnetic and electric field. 13. External chemical signals smell, taste; bacterial chemotaxis. 14. Internal chemical signals. Principles of neurochemistry, effects of hormones and cytokines. Principles of imunochemistry.
