Question

How do cells capture the energy released by cell respiration?

A. They store it in molecules of carbon dioxide.
B. They produce glucose.
C. The energy is released as pyruvate.
D. They produce ATP.

Answer 1

Cells capture the energy released from cellular respiration by producing ATP, which is used by the cell for various metabolic processes. About 36 to 38 ATP molecules are produced from the cellular respiration of one molecule of glucose.

Step-by-step explanation:

Cells capture the energy released by cell respiration primarily by producing ATP (adenosine triphosphate). ATP is a molecule that cells use to perform work and it represents a form of chemical energy that can be easily accessed by the cell for its metabolic processes. During cellular respiration, the energy that was once stored in glucose from photosynthesis is transferred to ATP. As the glucose is oxidized, energy is released and captured to form ATP from ADP (adenosine diphosphate) and inorganic phosphate. The process involves a series of reactions that slowly release the energy in controlled amounts, enabling the efficient production of ATP molecules. Typically, about 36 to 38 ATP molecules can be produced from the cellular respiration of one glucose molecule, which is then used to power various cellular activities.
