Question

Fermentation has a relatively low ATP yield compared to aerobic respiration because a. more reducing equivalents are used for anaerobic catabolism. b. less ATP is consumed during the first stage of aerobic catabolism. c. oxidative phosphorylation yields a lot of ATP. d. substrate-level phosphorylation yields a lot of ATP.

Answer 1

Answer:

c. Oxidative phosphorylation yields a lot of ATP

Explanation:

Fermentation is an anaerobic process that takes place in the anaerobic bacteria to produce an energy molecule called ATP.  The process of fermentation involves the breakdown of the glucose through glycolysis which produces 2 ATP molecules, NADH and Pyruvate molecules.

The process does not undergo further steps like the Citric acid cycle and the oxidative phosphorylation which forms the high number of ATP molecules. Since the organism which performs the fermentation does not undergo oxidative phosphorylation therefore the yield of ATP in the cell is very less.

Thus, Option-C is correct.
