atp is composed of
ATP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP). ATP is the most commonly used energy currency of cells from most organisms.It is formed from adenosine diphosphate (ADP) and inorganic phosphate (P i), and needs energy.TP synthase (EC 3.6.3.14) is an important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate (ATP).
