Here's why:
* Glucose contains a lot of chemical energy. When glucose is completely oxidized, it releases a large amount of energy.
* ATP is the primary energy currency of cells. Cells use ATP to power various metabolic processes.
* Aerobic respiration is highly efficient. This process breaks down glucose in the presence of oxygen, maximizing energy capture.
However, it's important to note that:
* Not all the energy is captured. Some energy is lost as heat during the process.
* Efficiency varies. The actual percentage of energy captured can vary slightly depending on factors like the specific organism and environmental conditions.
Overall, aerobic respiration is a highly efficient process that captures a significant portion of the energy stored in glucose.
