In the process of cellular respiration, glucose is broken down into simpler compounds. Respiration is carried on in the presence (aerobic) or absence (anaerobic) of free oxygen. a. True
b. False

a. True

Explanation:

Cellular Respiration is the process by which cells of all living organisms obtain the required energy for their metabolic activities. Respiration is a catabolic process whereby glucose is broken down to release Its high energy and used to synthesize a usable form of energy by the cell (ATP).

Cellular respiration occurs in living cells with oxygen (aerobic) or without oxygen (anaerobic). In aerobic respiration, three processes viz: Glycolysis, Kreb's cycle and Oxidative phosphorylation are involved. Oxygen is the final electron acceptor in the Electron transport chain of the Oxidative phosphorylation.

On the other hand, anaerobic respiration is employed by certain bacteria in the absence of oxygen. In anaerobic respiration, another final electron acceptor is used other than oxygen.

Both processes yield Adenosine triphosphate (ATP).

the answer is b.) hydrogen bonds between bases.
