Give full form of ATP.
ATP stands for Adenosine Triphosphate. This molecule serves as the primary energy currency of all living cells, storing and transferring energy needed for virtually every cellular process including muscle contraction, nerve impulse transmission, chemical synthesis, and active transport across membranes.
Structurally, ATP consists of adenosine (a nitrogenous base adenine attached to a ribose sugar) bonded to three phosphate groups. The high-energy bonds between the phosphate groups, particularly the terminal phosphate bond, store significant chemical energy. When this bond is broken through hydrolysis—converting ATP to ADP (Adenosine Diphosphate) and an inorganic phosphate—energy is released and made available for cellular work. Cells continuously regenerate ATP from ADP through cellular respiration in mitochondria, creating a constant cycle of energy storage and release that powers life processes.
