Complete Table 7.1 by matching every description to the appropriate letter. Descriptions: - product formed at the end of glycolysis - location in the cell where respiration happens in anaerobic conditions - product formed at the end of respiration in anaerobic conditions in yeast cells - compound that is used to reduce pyruvate - product formed at the end of respiration in anaerobic conditions in muscle cells - gas given off during alcoholic fermentation
(b)[2]
Anaerobic respiration in muscle cells during vigorous exercise can lead to an oxygen debt. After exercise, additional oxygen is taken in to repay the oxygen debt. Explain two ways in which the mammalian body makes use of this extra oxygen.
