How might a plant cope with the fact that the Calvin cycle uses more ATP than NADPH, yet produces roughly the same amount of both energy intermediates in photosystems I and II?
A. Plants often increase the amount of NADP reductase, thereby increasing NADPH production to match ATP output. B. Increase the electrochemical gradient for H+ across the thylakoid membrane, producing more ATP but not NADPH. C. Photosynthesis can revert from a noncyclic to cyclic electron flow, producing more ATP than NADPH. D. More pigment can be rapidly created for greater photosynthetic capacity, producing equal amounts of ATP and NADPH. E. Electron flow rate can be increased, increasing both ATP and NADPH production.
