|
Definition
ATP is produced via cellular respiration in the mitochondria and photosynthesis in chloroplasts.
Its functions are for intracellular energy transport for various metabolic processes including biosynthetic reactions, motility, and cell division. It is also used as a substrate by kinases that phosphorylate proteins and lipids, and by adenylate cyclase to produce cyclic AMP. |
