ATP is used when _
Correct answer: D. All of the above
- A. To synthesize the macromolecules
- B. To transport molecules and ions
- C. To perform mechanical work
- D. All of the above
Explanation
ATP (Adenosine Triphosphate) is a molecule that serves as the primary energy currency of the cell. It is used in various cellular processes to provide energy, for synthesizing macromolecules, ATP provides the energy needed for biosynthetic reactions that build complex molecules such as proteins, nucleic acids, and lipids.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
