2 An organic or inorganic electron donor is oxidized to CO2 using O2 ( or an O2 substitute) as the final electron acceptor What is Respiration? What is Respiration? An aerobic or anaerobic catabolic process ATP is produced by an electron transport system (ETS ), which generates PMF to form ATP by Oxidative Phosphorylation ETS ATP PMF e.g. C 6 H 12 O 6 + 6 O 2 => 6 CO 2 + 6 H 2 O +/- O2 Waste products : CO 2 , H 2 O, NO 2 -, …etc. (and Heat!!) Oxidative Phosphorylation Three Important Processes to Remember in Respiration Three Important Processes to Remember in Respiration 1. Carbon Flow As an organic compound is oxidized to CO2 generating reducing power (NADH, NAD(P)H, FADH) and carbon intermediates (see next slide -- the TCA cycle ). Some of the intermediate compounds will be used in biosynthesis.
