What does ATP stand for in cellular biology?

In cellular biology, ATP stands for adenosine triphosphate. This molecule serves as the primary energy carrier in all living organisms. It consists of an adenosine molecule bound to three phosphate groups, which store energy within the high-energy bonds between the phosphate groups. When a cell requires energy, ATP can be broken down into adenosine diphosphate (ADP) and an inorganic phosphate, releasing energy that powers various cellular processes such as muscle contraction, nerve impulse propagation, and biosynthesis. Understanding the role and structure of ATP is key for comprehending how cells harness and utilize energy for their functions, making it a fundamental concept in biology.
