WebNov 4, 2024 · Alkaline phosphatases are a group of isoenzymes, located on the outer layer of the cell membrane; they catalyze the hydrolysis of organic phosphate esters present in the extracellular space. Zinc and magnesium are important co-factors of this enzyme. Although alkaline phosphatases are present in dif … WebDec 30, 2024 · PEP is made because hydrolysis of the phosphate from 2PG does not release enough energy to drive phosphorylation of ADP to ATP. PEP hydrolysis, on the other hand, releases significantly more than needed. 10. Pyruvate kinase then transfers a high energy phosphate group from PEP to ADP, producing an ATP for use by the cell, and pyruvate.
