A. Glucose (partial answer - glucose is used as a reactant in cellular respiration, but it is not a product of the process)
B. Oxygen (partial answer - oxygen is used as a reactant in cellular respiration, but it is not a product of the process)
C. Water (correct answer)
D. Energy (correct answer)
E. Carbon dioxide (correct answer)
Cellular respiration is the process by which cells produce energy in the form of ATP (adenosine triphosphate) from glucose and other organic molecules. The process occurs in the mitochondria of cells and involves a series of reactions that convert glucose and oxygen into ATP, water, and carbon dioxide.
Glucose and oxygen are reactants in cellular respiration, meaning that they are consumed in the process. The products of cellular respiration are ATP, water, and carbon dioxide. Therefore, the correct answers are C, D, and E.
