Question

what are the reactants of cellular respiration? select all that apply.
atp
carbon dioxide gas
glucose
light energy
oxygen gas
water

Explanation:

Cellular respiration is a metabolic process. Its reactants are glucose and oxygen gas. Glucose ($C_6H_{12}O_6$) is broken down, and oxygen is used in the process. Water and carbon dioxide are products, not reactants. Light energy is used in photosynthesis, not cellular respiration. ATP is a product (energy currency) of cellular respiration, not a reactant.

Answer:

Oxygen gas, Glucose
