Which statement explains what aerobes use oxygen to do?

A. to provide the alcohol group added to organic compounds in fermentation

B. to insulate themselves in anaerobic environments

C. to oxidize organic compounds for the release of energy and/or as a terminal electron acceptor

D. to prevent free radicals from reacting with DNA and other vital molecules


Aerobic organisms are known to depend on oxygen to sustain life. These organisms are also known as aerobes, and they utilize oxygen in their metabolic processes.
