Which of the following represents an example of aerobic cellular respiration?

1. nitrogen + oxygen + glucose → methane + carbon

2. dioxide water + carbon dioxide + energy → glucose + oxygen + water

3. glucose + oxygen → water + carbon dioxide + energy

4. nitrogen + carbon dioxide + energy → methane + oxygen

5. water + carbon dioxide → glucose + oxygen + water + energy

Answer:3. glucose + oxygen → water + carbon dioxide + energy

Explanation:

The aerobic respiration is a metabolic process that occurs in the mitochondria of the cell. This involves the oxidation of glucose which is stored by the cell as an energy reservoir. It is a multi-step process which involves the break down of glucose into water, carbon dioxide and energy in the form of ATP molecules. The reactions involved in the aerobic respiration are catabolic reactions that is large glucose molecules are broken down into carbon dioxide and water releasing energy in the form of heat.
