Final product in aerobic respiration are carbon dioxide and water, whereas Lactic acid (animal cells), carbon dioxide and ethanol (plant cell) is the final product in anaerobic respiration. SomyaVishnoi2610 SomyaVishnoi2610 Explanation: Respiration in Yeast: The end products are 2C2H5OH(Ethanol) + CO2(Carbon dioxide)+2ATP. The chemical reaction transfers energy from glucose to the cell. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration. This anaerobic respiration fermentation helps in production of ethanol and Nicotinamide Adenine Dinucleotide (NAD The breakdown of glucose to 2 pyruvic acid molecules. The diagram below show an experimental set up to investigate a certain physiological process in plants. Qn 3. The cells of animals, plants, and many bacteria need oxygen (O2) to facilitate the energy-transfer during cellular respiration. Both fermentation and anaerobic respiration occur in the absence of oxygen to produce energy. Unlike aerobic respiration, anaerobic respiration does not need oxygen. Carbon dioxide and water. Krebs Cycle (Aerobic Pathway) Makes 2 ATP 3. Oxygen is used as the final electron acceptor at the end of the Electron Transport Chain. food molecules. Anaerobic respiration is the ability of an organism to produce energy in the form of Adenosine Triphosphate (ATP) without using oxygen. 3.Pyruvic acid is the end product of glycolysis. When I was solving MCQs for this chapter, it gave me a question: Anaerobic respiration in yeast produces- I chose ethanol, but it said that the correct option was alcohol. Explanation: When muscles exercise hard, the body is unable to supply sufficient oxygen resulting in anaerobic respiration. They now know, however, that your body fatigues to conserve this … C. Carbon dioxide, water and energy. Aerobic respiration requires oxygen and glucose to produce energy whereas in anaerobic respiration does not require oxygen but uses glucose to produce energy. A.
