Course objectives
At the end of the course students should be able tounderstand and explain the main types of energy transformations in living cells, with emphasis on mechanisms of coupling chemical or photochemical processes with a transport across biological membranes. It should also be able to justify the choice of experimental methods suitable to study a specific bioenergetic problem.
Syllabus
  • 1) History and the present status of bioenergetics. Energy conversions in living organisms: an overview and thermodynamic description. 2) Macroergic compounds. Mechanisms of substrate-level energy conservation. 3) Biomembranes: lipids, proteins and their mutual interactions. Determination of the structure of membrane-bound proteins. 4) Mechanisms of membrane transport. Transporters, channels, ionophores. Membrane-bound transport ATPases. Rotational catalysis in the proton-translocating ATPase. 5) Enzymes, prosthetic groups and electron carriers involved in important redox reactions. 6) Membrane-bound electron-transport chains. Approaches to the study of the electron-transport chains. Artificial electron donors and acceptors. The coupling of redox reaction with proton gradient formation. 7) Isolation, ultrastructure and metabolic activities of mitochondria. Transport of proteins, inorganic ions and metabolites across the mitochondrial membrane. 8) Mitochondrial respiration and oxidative phosphorylation. 9) Aerobic respiration in chemoorganotrophic and chemolithotrophic bacteria. 10) Anaerobic respiration. Regulation mechanisms in facultative anaerobes. 11) Bacteriorhodopsin-based photosynthesis. Anoxygenic and oxygenic photosynthesis dependent on (bacterio)chlorophyll, cooperation of two photosystems in oxygenic photosynthesis. 12) Metabolic cooperation of mitochondria, chloroplasts and cytoplasm. 13) Mechanochemical energy conversions. Thermogenesis in brown fat tissue. Bioluminiscence. Bioenergetics of sodium ion. 14) Evolution of bioenergetic processes. Bioenergetics and the cycles of biogenic elements in the nature.
