Glucose still goes through glycolysis which creates the pyruvic acid and net 2 ATP, but in order to regenerate more NAD the pyruvic acid is then broken down into lactic acid. The conversion of pyruvic acid to lactic acid requires NADH: Pyruvic Acid + NADH + H +---> Lactic Acid + NAD + This pyruvic acid normally made by transamination of amino acids, is intended for conversion into glucose by gluconeogenesis. This pathway is inhibited by low concentrations of pyruvic acid, since it has been converted to lactic acid. But it is an end product of glycolysis. Here, pyruvate (a metabolite of glucose) is reduced to lactic acid by accepting electrons from NADH, which oxidizes NADH back to NAD + to allow glycolysis to continue under anaerobic conditions. In homolactic pathway, lactic acid fermentation equation is. Which processes require oxygen? Check all that apply. c. atp. A. conversion of pyruvic acid to Acetyl CoA B.conversion of pyruvic acid to lactic acid C.conversion of acid to alcohol D.production of carbon dioxide in the citric acid cycle E.production of water in the electron transport chain F.production of pyruvic acid in … d. nadh. Glucose + 2 ADP + 2 P i → 2 lactate + 2 ATP. As you can see in the picture, the reaction from pyruvate to lactic acid requires an NADH molecule. If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Start studying Chapter 9 1-3 Test. In your muscles when you don't get enough oxygen, they will continue to work using lactic acid fermentation. Pyruvic acid is an intermediate product of both alcoholic and lactic acid fermentation. Check all that apply. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Which processes require oxygen? B is wrong because oxygen is used in AEROBIC, not anerobic conversion of pyruvate. C is wrong, just because ATP is not used A. conversion of pyruvic acid to Acetyl CoA B. conversion of pyruvic acid to lactic acid C. conversion of acid to alcohol D. production of carbon dioxide in the citric acid cycle E. production of water in the electron transport chain F. production of pyruvic acid … But there are several equations of Lactic acid fermentation, as lactic acid is produced in different ways. Lactic acid (also called lactate).The product of glycolysis in the cytoplasm is pyruvic acid (= pyruvate). Correct answers: 3 question: 39. the conversion of pyruvic acid into lactic acid requires a. alcohol. Some processes in our bodies require the use oxygen, others do not. b. oxygen. A is wrong, because a secondary alcohol IS created (its in the lactic acid) but an alcohol is not USED in the reaction. Muscle cells convert pyruvate into lactate. In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.
