The phosphate groups
Webb24 dec. 2024 · 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→ADP+Pi+ free energy; the calculated ∆G for the hydrolysis of 1 mole of ATP is -57 kJ/mol. Webb30 dec. 2024 · The phosphate group on the 1-carbon of 1,3-bisphosphoglycerate is transferred to ADP by phosphoglycerate kinase to make 3-phosphoglycerate and ATP (finally!). From the two molecules of G3P entering step 6, we get two molecules of ATP to provide energy for the cell in this step.
