Capitolo 21, Problema 47
Write the reaction for the hydrolysis of 1,3-bisphosphoglycerate coupled to the phosphorylation of ADP using the curved-arrow symbolism.
Guida verificata passo dopo passo1
Identify the reactants and products involved in the reaction. The hydrolysis of 1,3-bisphosphoglycerate involves breaking a high-energy phosphate bond, and the phosphorylation of ADP involves adding a phosphate group to ADP to form ATP.
Write the chemical equation for the hydrolysis of 1,3-bisphosphoglycerate. The reaction releases a phosphate group (Pi) and forms 3-phosphoglycerate. Represent this as: .
Write the chemical equation for the phosphorylation of ADP. This reaction uses the inorganic phosphate (Pi) released from the hydrolysis of 1,3-bisphosphoglycerate to convert ADP into ATP. Represent this as: .
Combine the two reactions into a single coupled reaction. The phosphate group released from 1,3-bisphosphoglycerate is directly used to phosphorylate ADP. The overall reaction can be written as: .
Use curved-arrow symbolism to show the movement of electrons during the reaction. Indicate the breaking of the bond between the phosphate group and 1,3-bisphosphoglycerate, and the formation of a new bond between the phosphate group and ADP. This step involves drawing the reaction mechanism, which includes showing the nucleophilic attack of ADP on the phosphate group and the subsequent release of 3-phosphoglycerate.
