Anaerobic Cell Respiration by Yeast BACKGROUND: Yeast are tiny single-celled (unicellular) fungi. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell. Anaerobic respiration is the process by which incomplete oxidation of respiratory substrate takes place. In aerobic organisms undergoing respiration, electrons are shuttled to an electron transport chain, and the final electron acceptor is oxygen. The carbon dioxide produced by yeast is used in the bread making industry. None of its nine steps involve the use of oxygen. However, some organisms have evolved to use other final electron acceptors… Yeast can undergo both aerobic and anaerobic respiration. The organisms in the Kingdom Fungi are not ... carbon dioxide are waste products produced by the yeast. Yeast converts glucose into ethanol and carbon dioxide. Consequently, the by-products of this process are lactic acid and ATP. Anaerobic respiration does not require oxygen to produce energy. - Definition & Examples. Anaerobic respiration is the respiration which occurs in the absence of oxygen. It is carried out by yeast and some bacteria. Initially the yeast cells are respiring aerobically because of the oxygen present in the air in the boiling tube. A cell that can perform aerobic respiration and which finds itself in the presence of oxygen will continue on to the aerobic citric acid cycle in the mitochondria. Anaerobic respiration in yeast Anaerobic respiration is economically important - many of our foods are produced by microorganisms respiring anaerobically.
