What is the major energy carrier molecule in most cells?

Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) is the major energy carrier molecule in most cells. It is produced during cellular respiration by the breakdown of glucose and other molecules. ATP is used to power cell processes, such as muscle contraction, cell division, and protein synthesis. Other molecules listed (such as glucose, pyruvate, and acetyl CoA) are involved in producing ATP, but do not serve as the primary energy carrier molecule. A kcalorie (D) is a unit of energy, not a molecule, and is commonly used to measure the energy content of food.
