Which statement explains what aerobes use oxygen to do?
a.) to insulate themselves in anaerobic enviroments
b.) to prevent free radicals from reacting with dna and other vital molecules
c.) to provide the alcohol group added to organic compounds in fermentation
d.) to oxidize organic compounds for the release of energy and/or as a terminal electron acceptor

Out of the 4 options provided for the give question, the correct option is Option d.) to oxidize organic compounds for the release of energy and as a terminal electron acceptor.

Explanation:

This can be explained as Aerobes make use of oxygen for their growth and survival.

In cellular respiration, these are used for oxidation of substrate such as fats, sugar, etc in order to generate energy which is generated in the form of chemical compound Adenosin Tri Phosphate(ATP)

In transport system of electrons, electron movement results in proton pumping for the generation of ATP. This process requires oxygen as aerobes makes use of oxygen as electron acceptor ion in the ET(Electron Transport) system

then that particular organisms become extinct.
