Figure 2.

Number of metabolic and transport reactions distributed between compartments in the bundle sheath and mesophyll cell types. The numbers of metabolic and transport reactions are shown for each compartment. Integral membrane proteins are counted for the compartment in which the main biotransformation occurs. For example, the ATP synthase associated with the mitochondrial electron transport chain is counted as a metabolic reaction in the mitochondrion, not the inner mitochondrial membrane (IMM).
