Fermentation and cellular respiration begin the same way, with glycolysis. NADH and FADH2 Model: Eukaryote Cell How many times will the Krebs cycle take place for each molecule of In yeast cells (the yeast used for baking bread and producing alcoholic beverages), glucose can be metabolized through cellular respiration as in other cells. Cellular Respiration & Fermentation. pyruvate molecule? Yeast consume the sugar in wort, and turn that sugar into CO2, alcohol, and flavor. Alcoholic fermentation is the best known of the fermentation processes, and is involved in several important transformation, stabilization, and conservation processes for sugar-rich substrates, such as fruit, and fruit and vegetable juices. c. oxygen. Aerobic pathways require oxygen to produce energy. [You may copy but again you must have the web page next to it.] Lactic acid and alcoholic fermentation are two mechanisms involved in the respiration in the absence of oxygen. Lactic acid fermentation refers to a metabolic process by which glucose is converted into the metabolite: lactate and cellular energy. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration. The chemical equation for cellular respiration is: 6O 2 + C 6 H 12 O 6-->6CO 2 + 6H 2 O + Energy Using this information, which statement best compares cellular respiration and photosynthesis?
