Question | Answer |
total of all chemical reactions occurring in cell | metabolism |
breakdown of larger, more complex molecules into smaller, simpler ones; energy is released and some is trapped and made available for work | catabolism |
synthesis of complex molecules from simpler ones with the input of energy | anabolism |
most respiration involves use of an | electron transport chain |
in _____, final electron acceptor is oxygen | aerobic respiration |
in _____, final electron acceptor is different exogenous acceptor such as NO3-, SO42-, CO2, Fe3+ or SeO4(2-); organic acceptors may also be used | anaerobic respiration |
as electrons pass through the electron transport chain to the final electron acceptor, a _________ is generated and used to synthesize ATP | proton motive force |
Use inorganic electron source, can be aerobic or anaerobic organism (mostly aerobic) | Chemolithotroph |
uses an endogenous electron acceptor | fermentation |
usually an intermediate of the pathway used to oxidize the organic energy source e.g., pyruvate | endogenous electron acceptor |
does NOT involve the use of an electron transport chain nor the generation of a proton motive force | fermentation |
in fermentation ATP is synthesized only by | substrate-level phosphorylation |
what stage of aerobic catabolism does large molecules (polymers)->small molecules (monomers) | 1st stage |
what stage of aerobic catabolism does initial oxidation and degradation to pyruvate | 2nd stage |
what stage of aerobic catabolism oxidation and degradation of pyruvate by the tricarboxylic acid cycle (TCA cycle) | 3rd stage |
