WebView history Lactate dehydrogenase ( LDH or LD) is an enzyme found in nearly all living cells. LDH catalyzes the conversion of lactate to pyruvate and back, as it converts NAD + to NADH and back. A dehydrogenase is an … WebThe formation of lactate is the fate of much of the pyruvate formed from glucose under conditions of maximum muscle exertion when oxygen is limiting, but as much as possible will continue to undergo complete oxidation. Many tumors have a low capacity for oxidative metabolism, so that much of the energy-yielding metabolism in the tumor is anaerobic.

During high rates of glucose oxidation, NADH levels become high, and the redox state of mitochondria triggers inhibition of FA oxidation. WebAlternatively, NADH is oxidized back to NAD+in the cytoplasm via lactate dehydrogenase, correspondingly producing lactate from pyruvate. The products of glycolysis are two moles of pyruvate, 2 moles of NADH and two moles of ATP. Pyruvate has multiple possible fates. In lactate dehydrogenase reaction pyruvate is reduced to lactate. prepare a minutes of meeting
