ATP is a molecule with a lot of chemical energy.

ATP stands for Adenosine Tri Phosphate, and that third phosphate is bonded to the other two with a very high energy bond, so a lot of energy is released when that bond is broken. https://www.alamy.com/stock-photo-adp-molecule-adenosine-phosphate-20789905.html Think of it as the “energy currency” of the cell. Please refer to the The conversion of these two molecules plays a critical role in supplying energy for many processes of life. ATP breakdown into ADP and P i is called hydrolysis because it consumes a water molecule (hydro-, meaning “water”, and lysis, meaning “separation”). ADP is the end-product that results when ATP loses one of its phosphate groups located at the end of the molecule. ATP hydrolysis is the catabolic reaction process by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released by splitting these bonds, for example in muscles, by producing work in the form of mechanical energy.The product is adenosine diphosphate (ADP) and an inorganic phosphate, orthophosphate (P i).

When the third phosphate is removed from ATP, you get ADP, which stands for Adenosine Di Phosphate. This is an example of regulation by covalent modification of an enzyme since the action of ATP here is to phosphorylate, and consequently to inactivate, the isocitrate dehydrogenase. ADP can be converted, or powered back to ATP through the process of releasing the chemical energy available in food; in humans this is constantly performed via aerobic respiration in the mitochondria.

The deletion of one of ATP’s phosphorus bonds generates approximately 7.3 kilocalories per Mole of ATP.

Adenosine Triphosphate (ATP) : ATP is the primary energy currency of the cell. ATP (Adenosine tri-phosphate) is an important molecule found in all living things. Each of the compounds is composed of the nucleotide base adenine linked to the sugar ribose, which in turn is linked to a linear “tail” of one,…

Animals use the energy released in the breakdown of glucose and other molecules to convert ADP to ATP, which can then be used to fuel necessary growth and cell maintenance.
