Question

J.___ The final electron acceptor, for the electron transport chain, in anaerobic respiration is almost exclusively an organic molecule and usually NAD+.

True or false ^^

Answer 1

Answer: False.


Explanation: In anaerobic respiration, the final electron acceptor is typically an inorganic molecule such as sulfate, nitrate, or carbon dioxide. In fermentation, which is also a form of anaerobic respiration, the final electron acceptor is an organic molecule such as pyruvate or acetaldehyde. NAD+ is not a final electron acceptor, but rather a coenzyme that shuttles electrons between metabolic pathways.
