Using Fig. 8.1, identify the cell part where glucose is changed into pyruvate.
Using Fig. 8.1, explain why pyruvate must be converted to lactate when oxygen is absent.
Using Fig. 8.1, identify the enzyme that catalyses the conversion of pyruvate to lactate.
Using Fig. 8.1, name the reaction type and the kind of bonds formed when glucose molecules are joined to make glycogen.
Describe how anaerobic respiration in yeast cells is different from anaerobic respiration in mammalian cells.
The respiratory quotient (RQ) is used to work out which respiratory substrate, such as carbohydrate or lipid, an organism is using at a given time. State how the RQ is calculated.
State the usual RQ values for the respiration of carbohydrates and lipids.
Suggest what would happen to the RQ value when respiration changes to anaerobic.
