Question

What are the reactants of cellular respiration?

Answer 1

Answer:

Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.

Answer 2

The reactants of cellular respiration are oxygen and glucose.

Explanation:

• The process of the cells converting sugars into energy is called cellular respiration.
• Cellular respiration consists of three steps.
• In first step, in the cytoplasm, the glucose is broken down and this process is called glycolysis.
• In second step, in the mitochondria, the pyruvate molecules are transported.
• In third step, the energy is entered into electron transport chain and ATP is produced from this energy.
• In the process of converting glucose into ATP, oxygen is needed.
• When an organism is breathing, oxygen is entered into the body.
• When an organism is eating, glucose enters into the body.
• Hence, oxygen and glucose are reactants whereas carbon dioxide and water are the products.
• The chemical reaction is, $C_{6}H_{12}O_{6}+6O_{2}$ → $6CO_{2}+6H_{2}O$.
