Unformatted text preview: - 1 - Cells use three different catabolic pathways to extract free energy from nutrients. 1. aerobic cellular respiration 2. anaerobic cellular respiration 3. fermentation Aerobic Cellular Respiration- redox process in which hydrogen is transferred from glucose to oxygen- glucose is oxidized and oxygen is reduced- the overall pathway results in the formation of (a) CO 2 from the organic substrate (b) H 2 O from the reduction of oxygen (c) a substantial amount of energy (in the form of ATP)- the classic equation is: C 6 H 12 O 6 + 6O 2 6CO 2 + 6H 2 O + energy (36 or 38 ATP and heat)- requires an external electron acceptor (fermentation does not it balances itself); molecular oxygen serves as the terminal electron acceptor - in anaerobic cellular respiration, nitrate or sulfate serve as the terminal electron acceptor Besides redox reactions, the following reactions occur during cellular respiration. 1. Dehydrogenation Reactions- reactions in which 2 Hs (actually, 2 electrons and 2 protons) are removed from the substrate and...
