Cellular Respiration is the process in which cells produce the energy they need to survive. In cellular respiration, cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP.

What does the passage and diagram above best imply?

A. Oxygen and glucose are both products of cellular respiration

B. Cellular respiration refers to the metabolic reactions and processes which occur in the nucleus of organisms.

C. Cellular respiration is a process that converts glucose into chemical energy (ATP) in the chloroplast of the cell

D. The main product of cellular respiration is ATP waste products include carbon dioxide and water
