Answer to Question #198575 in Biology for hen

Question

Which of the following statements A to D describes and explains the relative yield of ATP in anaerobic and aerobic respiration?

A)   Anaerobic respiration produces less ATP per molecule of glucose because lactate is converted to pyruvate

B)   Anaerobic respiration produces less ATP per molecule of glucose because NAD is not regenerated in oxidative phosphorylation

C)   Anaerobic respiration produces more ATP per molecule of glucose because NAD is regenerated in oxidative phosphorylation 

D)   Anaerobic respiration produces more ATP per molecule of glucose because pyruvate is converted to lactate 

Answer 1

B)   Anaerobic respiration produces less ATP per molecule of glucose because NAD is not regenerated in oxidative phosphorylation.

Glycolysis requires NAD⁺ that cannot be regenerated completely during the process of anaerobic respiration.
