Question

Quizplus · Accepted Answer

Adenosine triphosphate (ATP) is a purine derivative that serves as the main energy currency of the cell. It is produced from the breakdown of fuel molecules and transfers energy to cellular processes, such as muscle contractions and protein synthesis. It is also involved in signal transduction pathways and acts as a coenzyme in various metabolic reactions.
