which of the following represent the reactants (ingredients) necessary for cellular respiration?

• hydrogen sulfide, carbon dioxide, and water
• starch and enzymes
• carbon dioxide, water, and oxygen
• glucose and oxygen

Explanation:

Cellular respiration is the process where cells break down glucose to release energy, using oxygen as a key reactant. The chemical equation for aerobic cellular respiration is $\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Energy}$, confirming glucose and oxygen are the required reactants. The other options list either products of respiration, unrelated substances, or incorrect compounds.

Answer:

D. glucose and oxygen
