Question

which of the statements is a simplified equation for cellular respiration?
glucose + oxygen → carbon dioxide + water
glucose + nitrogen → carbon monoxide + water
carbon dioxide + water + light → glucose + oxygen
protein + water → amino acids + carbon dioxide

Explanation:

Cellular respiration is the process by which cells break down glucose in the presence of oxygen to produce carbon dioxide and water, releasing energy. The correct equation represents this process. The other options have incorrect reactants (like nitrogen instead of oxygen) or represent other biological processes (such as photosynthesis in the case of carbon - dioxide + water + light → glucose + oxygen).

Answer:

glucose + oxygen → carbon dioxide + water
