Question

Which statement best summarizes cellular respiration?

Answer 1

Answer:

The answer is (a). The chemical potential energy stored in organic molecules is converted to chemical energy that can be used to do the work of the cell.

Explanation:

Cellular respiration is the process by which organisms combine oxygen with foodstuff molecules while diverting the chemical energy in these substances into life-sustaining activities and removing carbon dioxide and water as waste products. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bond, especially in molecular oxygen,  are replaced by stronger bonds in the products.
