ADP is combined with a phosphate to formATP in the reaction ADP+Pi+freeenergy→ATP+H2O. The energy released from the hydrolysisof ATP into ADP is used to perform cellular work,usually by coupling the exergonic reaction of ATP hydrolysiswith endergonic reactions.
Keeping this in view, what is added to ADP to make ATP?
Answer and Explanation: ADP (adenosinediphosphate) becomes ATP (adenosine triphosphate) when athird phosphate group is added.
Besides, what is the relationship between ADP and ATP?
Adenosine triphosphate (ATP) is the main energycarrier molecule used living things. The difference betweenATP and ADP, or adenosine diphosphate, is found in thenumber of phosphate groups, 3 for ATP and 2 forADP.
When the terminal (third) phosphate is cut loose,ATP becomes ADP (Adenosine diphosphate; di= two), andthe stored energy is released for some biological process toutilize.
