To determine the correct formula for cellular respiration, we need to understand the process of cellular respiration. Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP (adenosine triphosphate), which is the cell's main source of energy.
Looking at the options:
- Option 1: Carbon dioxide + water + ATP → glucose + oxygen. This is not the correct formula, as it suggests that cellular respiration is a reverse process, converting the products of respiration (carbon dioxide and water) back into glucose and oxygen. This is not what happens in cellular respiration.
- Option 2: Glucose + oxygen → carbon dioxide + water + ATP. This is the correct formula for cellular respiration. Glucose and oxygen are combined to produce carbon dioxide, water, and ATP.
- Option 3: Carbon dioxide + glucose → oxygen + water + ATP. This formula is not correct. It suggests that carbon dioxide and glucose combine to produce oxygen and water, which is the opposite of cellular respiration.
- Option 4: Glucose + water → oxygen + carbon dioxide + ATP. This formula is also incorrect. It suggests that glucose and water combine to produce oxygen, carbon dioxide, and ATP, which is not what happens in cellular respiration.
Therefore, the correct formula for cellular respiration is: Glucose + oxygen → carbon dioxide + water + ATP.
