ATP to ADP – Energy Release. This is done by a simple process, in which one of the 2phosphate molecules is broken off, therefore reducing the ATP from 3 phosphates to 2, forming ADP (Adenosine Diphosphate after removing one of the phosphates {Pi}). This is commonly written as ADP + Pi.
Essentially, the energy released from the ATP hydrolysis provides the energy required to power the pump and transport Na + and K + ions. ATP performs cellular work using this basic form of energy coupling through phosphorylation. The sodium-potassium pump is an example of ATP powering cellular work.

ADP is combined with a phosphate to form ATP in the reaction ADP+Pi+free energy→ATP+H2O. The energy released from the hydrolysis of ATP into ADP is used to perform cellular work, usually by coupling the exergonic reaction of ATP hydrolysis with endergonic reactions.
Learn about the ATP and ADP diagram, including the molecular structure and function of these important molecules in cellular energy metabolism. Understand the processes of ATP hydrolysis and ADP phosphorylation and their roles in cellular respiration and other metabolic pathways.
Overview of oxidative phosphorylation. The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis.
The answer lies with an energy-supplying molecule called adenosine triphosphate, or ATP. ATP is a small, relatively simple molecule (Figure 6.4.1 6.4. 1), but within some of its bonds, it contains the potential for a quick burst of energy that can be harnessed to perform cellular work.
