Suppose that the concentration of CO2 available for the Calvin cycle decreased by 50% (because the stomata closed to conserve water).
Which statement correctly describes how O2 production would be affected? (Assume that the light intensity does not change.)
A. The rate of O2 production would remain the same because the light reactions are independent of the Calvin cycle.
B. The rate of O2 production would decrease because the rate of ADP and NADP+ production by the Calvin cycle would decrease.
C. The rate of O2 production would decrease because the rate of G3P production by the Calvin cycle would decrease.
D. The rate of O2 production would remain the same because the light intensity did not change.
