Following are some facts regarding C3 and C4 Plants

a.) In C4 plants the reduction is caused by the additional energy requirements such as 1 ATP per CO2 from C3 plants

b.) C4 leaves are exposed to low O2 concentrations, the quantum yields for CO2 fixation remain constant while C3 leaves are exposed to low O2 concentrations quantum yield increases

c.) C3 leaves are exposed to low O2 concentrations, photorespiration is maximized
