Which of the following is a reactant of cellular respiration? (1 point)

Responses

carbon dioxide.
carbon dioxide.

energy.
energy.

water.
water.

oxygen.

oxygen.

The correct answer is oxygen.

The reactant of cellular respiration are the substances that are needed for the process to occur. In the given options, the reactant of cellular respiration is oxygen. To determine this, we can recall the equation for cellular respiration:

Glucose + Oxygen -> Carbon Dioxide + Water + Energy

In this equation, glucose is the fuel molecule that is being broken down, and oxygen is needed as a reactant for the process. Water and carbon dioxide are the byproducts of cellular respiration. Therefore, the correct answer is oxygen.
