Cellular respiration is the process of breaking down food such as
glucose into carbon dioxide and oxygen. During the process, cellular respiration
also releases energy in the form of ATP (adenosine triphosphate) for use by all
energy consuming activities of the cell. It is found in the simultaneous process
of Gycolysis and Kreb’s cycle. Glycolysis is the breakdown of glucose to two
pyruvic acids. These two pyruvic acids will be used for the production of
carbon dioxide and water in Kreb’s cycle. The answer is letter A.
