Document Summary
Atp does this the most: atp = energy currency not long term. Turn over is fast: atp consists of an adenine molecule, a ribose molecule, and three phosphate groups bonded to one another, when the terminal phosphate group is split off. 2018 oxidation is usually an exergonic (energy-releasing) reaction energy released from oxidative reactions powers generate of atp as a phosphate group is added to. Three ways atp can be generated: substrate-level phosphorylation generates atp by transferring a high-energy phosphate group from an intermediate phosphorylated metabolic compound a substrate directly to adp. In human cells, this process occurs in the cytosol: oxidative phosphorylation removes electrons from organic compounds and passes them through a series of electron acceptors, called the electron transport chain, to molecules of oxygen (o2). 1st step 6 carbon glucose sugar undergoes phosphorylation (breaks into smaller phosphate molecules) using two atp molecules = results in 3 carbon compound (pyruvic acid) .
