RQ values for a range of respiratory substrates can be worked out. Table 5.1 shows: • the formulae of four respiratory substrates • how many oxygen molecules ($\text{O}_2$) are required to respire each substrate fully to carbon dioxide and water. Using Table 5.1, Name the respiratory substrate with the highest RQ and the respiratory substrate with the lowest RQ.

Under anaerobic conditions, ATP generation in mammals and yeast depends on glycolysis and fermentation. Describe the similarities and differences between fermentation in mammals and in yeast.
