WebAug 15, 2024 · Via enzyme: pyruvate kinase; Produces 2 ATP; Stimulated by fructose 1,6-bisphosphate; Inhibited by ATP and alanine; The net reaction for glycolysis: glucose + 2 P i + 2 ADP + 2 NAD + → 2 pyruvate + 2 ATP + 2 NADH + 2 H + + 2 H2O. In glycolysis, 2 ATP are invested to gain 4 ATP. In total, there is a net gain of 2 ATP per 1 molecule of glucose. Pyruvate kinase is the enzyme involved in the last step of glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to adenosine diphosphate (ADP), yielding one molecule of pyruvate and one molecule of ATP. Pyruvate kinase was inappropriately named (inconsistently with a … See more Four isozymes of pyruvate kinase expressed in vertebrates: L (liver), R (erythrocytes), M1 (muscle and brain) and M2 (early fetal tissue and most adult tissues).
