Check all that apply. This pathway is inhibited by low concentrations of pyruvic acid, since it has been converted to lactic acid. Glucose + 2 ADP + 2 P i → 2 lactate + 2 ATP. c. atp. Which processes require oxygen? Muscle cells convert pyruvate into lactate. In your muscles when you don't get enough oxygen, they will continue to work using lactic acid fermentation. 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. In homolactic pathway, lactic acid fermentation equation is. If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. A is wrong, because a secondary alcohol IS created (its in the lactic acid) but an alcohol is not USED in the reaction. C is wrong, just because ATP is not used Learn vocabulary, terms, and more with flashcards, games, and other study tools. 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 … Some processes in our bodies require the use oxygen, others do not. B is wrong because oxygen is used in AEROBIC, not anerobic conversion of pyruvate. d. nadh. Correct answers: 3 question: 39. the conversion of pyruvic acid into lactic acid requires a. alcohol. Check all that apply. Which processes require oxygen? 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. But there are several equations of Lactic acid fermentation, as lactic acid is produced in different ways. Find an answer to your question During fermentation, the conversion of pyruvate into lactic acid requires... a. NADH b. carbon dioxide c. ATP d. oxygen gas As you can see in the picture, the reaction from pyruvate to lactic acid requires an NADH molecule. But it is an end product of glycolysis. 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. 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. b. oxygen. Lactic acid (also called lactate).The product of glycolysis in the cytoplasm is pyruvic acid (= pyruvate). Pyruvic acid is an intermediate product of both alcoholic and lactic acid fermentation. 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 … Start studying Chapter 9 1-3 Test.
