(i) Potassium hydroxide Anaerobic respiration (also called intra-molecular respiration) is an incomplete respiration as it releases only part of the free energy of the substrate, and it has among its end products something that can be further oxidized to yield additional energy. The results are shown in the graph below. (b) State the role of the following in the experiment. The two common products are ethyl alco­hol and lactic acid. The products of anaerobic respiration are lactic acid, carbon dioxide, and water. (i) The high blood flow through cardiac and skeletal muscles during strenuous exercises. How are the mitochondria adapted to their function? In both plants and animals, the pyruvates that are produced by glycolysis are either oxidized by the link reaction and citric acid cycle in mitochondria, or are reduced via fermentation in the cytosol, In mitochondria, it is aerobic respiration that occurs, and fermentation is not a form of anaerobic respiration. Aerobic Respiration. 2. Write in the space provided in the diagram. (ii) During formation of phosphoenol pyruvate. 1. alcohol fermentation, lactic acid fermentation. Anaerobic respiration is also common in bacteria that live in environments without oxygen; depending on the bacteria, the products of their respiration include nitrite, nitrogen gas, hydrogen sulfide, methane and acetic acid.
