Limited number of ATP molecules is generated per In micro-organisms the term fermentation is more commonly used where anaerobic respiration is known after the name of product like alco­holic fermentation, lactic acid fermentation. alcoholic drinks. Follow me to get follow back!! Many species of yeast (Saccharomyces) (b) At least one of the products of anaerobic respiration is organic. Due to lack of oxygen, they carry out respiration in the absence of oxygen to produce the energy they require, which is referred to as anaerobic respiration. The two common products are ethyl alco­hol and lactic acid. This type with the help of micro-organisms or their enzymes. muscles of vertebrates produce lactic acid from pyruvic acid (Table 14.3). Ethanol (d) ATP formation does not occur during regeneration of NAD+. No C02 is produced. Anaerobic respiration builds up an oxygen debt and that has to paid off and clearly the sooner, the better - e.g, when lifting weights in your arms, your muscles will start to burn. The difference in products is the primary difference between the two. It is the process of release of energy in enzymatically controlled step-wise incomplete degradation of organic food without oxygen being used as oxidant. and it is used for Carbon fixation in photosynthesis. Higher organism like plants can not perform anaerobic respiration for long. (xi) Decom­position of organic remains is carried out by fermentation. Share Your PPT File.
