The net end products of glycolysis are: 2 pyruvate, 2 ATP and 2 NADH. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration. Plant cells and yeast - carbon dioxide and ethanol. Aerobic respiration is the complete oxidation of sugars in presence of oxygen. The end product of aerobic respiration is carbon dioxide, water and energy. Please answer this doubt as soon as possible, as I need an answer. In this case, it occurs in the absence of oxygen resulting the end products of ethyl alcohol and CO 2 in plants and lactic acid (in animals) with very slight energy. The products of anaerobic respiration in yeast are ethanol and carbon dioxide. Researchers once thought that running out of adenosine triphosphate created feelings of fatigue. SomyaVishnoi2610 SomyaVishnoi2610 Explanation: Respiration in Yeast: The end products are 2C2H5OH(Ethanol) + CO2(Carbon dioxide)+2ATP. In anaerobic respiration 59 Kcal of energy is liberated per mole of glucose. Thus, pyruvic acid is theintermediate product of aerobicrespiration. Unlike aerobic respiration, anaerobic respiration does not need oxygen. Thanks for A2A… The first stage of aerobic respiration is glycolysis in which glucose molecule is broken down into two molecules of pyruvic acid. In anaerobic respiration, the end-products are ethanol and carbon dioxide in plants whereas the end-products are lactic acid only in animals.
