What does adenosine triphosphate do?

• A. Provides energy to cells and converts energy to carbon dioxide
• B. Stores genetic information
• C. Builds proteins
• D. Regulates metabolism of fats

Answer: (A)

Adenosine triphosphate acts as the cell’s energy currency, storing energy in its high‑energy phosphate bonds and releasing it when a phosphate is removed. This energy powers essential cellular tasks such as muscle contraction, active transport across membranes, and the synthesis of biomolecules. The statement captures ATP’s primary role: providing energy to cells. Energy isn’t directly converted into carbon dioxide by ATP; CO2 is produced during cellular respiration when nutrients are oxidized, and the released energy is captured as ATP for use. The other ideas aren’t ATP’s main function: storing genetic information is the job of DNA/RNA, protein synthesis is a process driven by ribosomes using energy from ATP but not performed by ATP itself, and fat metabolism is regulated by enzymes and signaling pathways rather than ATP alone.
