- Course objectives
- The course aims to provide students with a basic understanding of the principles governing energy conversion in living systems. Emphasis is placed on chemiosmotic mechanisms occurring on specialized energy-transducing membranes in bacteria, animals and plants. The existing connections between bioenergetic processes and biogeochemical cycles of biogenic elements in nature are also mentioned.
- Learning outcomes
- By the end of the course, the student will be able to demonstrate knowledge and understanding of the molecular machinery of respiratory and photosynthetic electron-transport chains, ATP synthase, and other membrane transport systems. The student is expected to have understood the main aspects of the storage and conversion of various forms of energy in cells within a broader ecological context.
- 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.
