Detailed explanation-1: -Exactly how much free energy is released with the hydrolysis of ATP, and how is that free energy used to do cellular work? The calculated ∆G for the hydrolysis of one mole of ATP into ADP and Pi is −7.3 kcal/mole (−30.5 kJ/mol).

Detailed explanation-2: -The hydrolysis of one molecule of ATP to Adenosine Diphosphate ADP and inorganic phosphate releases 7.3 kcal /mol of energy.

Detailed explanation-3: -One glucose molecule yields four ATP molecules in total during glycolysis. Since 2 ATP molecules are used up in the first phase of glycolysis, there is a net gain of 2 ATP molecules. In addition, glycolysis results in the production of 2 NADH molecules.

Detailed explanation-4: -Adenosine triphosphate is composed of the nitrogenous base adenine, the five-carbon sugar ribose, and three phosphate groups. ATP is hydrolyzed to ADP in the reaction ATP+H2O
