ATP as the immediate energy currency

ATP as the immediate energy currency

ATP cycle showing hydrolysis of ATP to ADP and inorganic phosphate, regeneration of ATP, and ATP-powered processes such as active transport and protein synthesis

Energy enters most ecosystems as sunlight and is eventually stored in biomass. Inside cells, the immediate energy carrier that powers reactions is ATP, so cells do not usually use glucose directly in each reaction.
