Verified step by step guidance

Understand the process of cellular respiration: Cellular respiration is a metabolic process that converts glucose and oxygen into ATP (adenosine triphosphate), water, and carbon dioxide. It occurs in the mitochondria of cells.

Recognize the efficiency of ATP production: During cellular respiration, not all the energy from glucose is converted into ATP. A significant portion of energy is lost as heat.

Identify the typical energy loss: In cellular respiration, approximately 60% of the energy from glucose is lost as heat. This is a normal part of the process, as the conversion of energy is not 100% efficient.

Consider the options given: Compare the percentage of energy lost as heat (approximately 60%) with the options provided in the problem.

Select the correct answer: Based on the understanding that approximately 60% of energy is lost as heat during cellular respiration, choose the option that matches this percentage.
