The purpose of cellular respiration is to enable cells to create and use

O ATP

ODNA

oxygen

O carbon dioxide

Answer: ATP

Explanation: Cellular respiration is a biochemical process in which glucose is broken down into a form of energy usable by the cells. The energy produced is in form of ATP. ATP is adenosine triphosphate. It is a process of oxidizing food molecules such as glucose to yield carbon dioxide and water with a release of energy in form of ATP. Cellular respiration has four stages: glycolysis, oxidation of pyruvate to acetyl CoA, Krebs cycle or citric acid cycle and electron transport chain.
