Microbial Degradation of Hydrocarbons Cannot Take Place Using ______ as the Electron

Question

Microbial degradation of hydrocarbons cannot take place using ______ as the electron acceptor.
A)oxygen
B)carbon dioxide
C)nitrate
D)sulfate

Accepted Answer

Microbial degradation of hydrocarbons typically involves the use of an electron acceptor to facilitate the breakdown process. Common electron acceptors include oxygen (in aerobic processes), nitrate, and sulfate (in anaerobic processes). Carbon dioxide, however, is not used as an electron acceptor in the microbial degradation of hydrocarbons; instead, it is often a byproduct of these processes.
