All of the Following are Required in the Reactions of Microbial

Question

All of the following are required in the reactions of microbial respiration EXCEPT
A)electron transport system.
B)cytochromes.
C)a source of electrons.
D)oxygen.
E)final electron acceptor.

Accepted Answer

Microbial respiration can occur with or without oxygen. Oxygen is only required in aerobic respiration as the final electron acceptor, but is not required in anaerobic respiration where alternative electron acceptors are used. Therefore, option D (oxygen) is not always required in the reactions of microbial respiration.
