Detailed explanation-1: -ATP Hydrolysis and Synthesis The reverse reaction combines ADP + Pi to regenerate ATP from ADP. Since ATP hydrolysis releases energy, ATP synthesis must require an input of free energy. The phosphorylation (or condensation of phosphate groups onto AMP) is an endergonic process.
Detailed explanation-2: -The hydrolysis of ATP into ADP and inorganic phosphate is an endergonic reaction because there is a positive change in free energy between products and reactants.
Detailed explanation-3: -ATP synthesis is an endergonic reaction because to form a high energy bond, energy is required.
Detailed explanation-4: -An endergonic reaction is one that requires free energy to proceed. An example of an endergonic reaction of biological interest is photosynthesis. Photosynthetic organisms conduct this reaction by using solar photons to drive the reduction of carbon dioxide to glucose and the oxidation of water to oxygen.
