Why is complete breakdown of food possible in aerobic respiration?
Answer and explanation
Correct answer: Because oxygen is present
In aerobic respiration, glucose is broken down in the presence of oxygen through a series of reactions, ultimately producing carbon dioxide and water. Oxygen acts as the final acceptor in the energy-releasing pathway, allowing glucose to be oxidised completely and releasing much more energy than anaerobic respiration. Hence A is correct; light, chlorophyll and closed stomata are not requirements for this process in animal cells.
