An Organism That Requires Chemical Nutrients Which Serve as Final

Question

An organism that requires chemical nutrients which serve as final electron acceptors is a(n)
A) chemotroph.
B) phototroph.
C) lithotroph.
D) autotroph.
E) aerobe.

Accepted Answer

Chemotrophs are organisms that obtain energy by oxidizing electron donors in their environments. These electron donors can be organic or inorganic chemicals. In the process, the chemical energy is converted to ATP through cellular respiration, where chemical nutrients serve as final electron acceptors.
