Complete Table 7.1 by pairing each description with a letter from A to J so that the correct structure or compound is identified. Descriptions: • final product of glycolysis • place in the cell where respiration in anaerobic conditions takes place • final product of respiration in anaerobic conditions in yeast cells • compound that reduces pyruvate • final product of respiration in anaerobic conditions in muscle cells • gas given off in alcoholic fermentation Each letter may be used once, more than once, or not used at all.
During vigorous exercise, respiration in anaerobic conditions in muscle cells can produce an oxygen debt. After exercise, extra oxygen is taken in to repay the oxygen debt. Explain two ways in which the mammalian body makes use of this extra oxygen.
