Multiple Choice

Each ATP molecule contains about 1% of the amount of chemical energy available from the complete oxidation of a single glucose molecule. Cellular respiration produces about 32 ATP from one glucose molecule. What happens to the rest of the energy in glucose?

It is stored as fat.

It is used to make water from hydrogen ions and oxygen.

It is released as carbon dioxide and water.

It is converted to starch.

It is converted to heat.

Verified step by step guidance

Begin by understanding the process of cellular respiration, which is the metabolic pathway that converts glucose into ATP, the energy currency of the cell.

Recognize that during cellular respiration, glucose is oxidized, and energy is released. This energy is used to synthesize ATP molecules, but not all energy from glucose is captured in ATP.

Note that the complete oxidation of glucose involves several stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. Each stage contributes to the production of ATP, but also results in the release of energy in other forms.

Understand that the energy not captured in ATP is primarily released as heat. This is a natural consequence of energy transformations, as some energy is always lost as heat due to the second law of thermodynamics.

Conclude that the rest of the energy from glucose, which is not stored in ATP, is dissipated as heat, helping maintain body temperature and contributing to the overall energy balance in the organism.
