Question

Quizplus · Accepted Answer

Respiration is a metabolic process that converts glucose and oxygen into ATP (adenosine triphosphate), carbon dioxide, and water. It takes place in the cytoplasm and mitochondria of cells. The overall equation for respiration is:

C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP

This means that respiration involves the chemical reaction between oxygen (O2) and carbohydrates (represented here by glucose, C6H12O6) that produces ATP, carbon dioxide (CO2), and water (H2O). Heat is also produced as a byproduct of this reaction. Therefore, Option B is the correct answer.
