ADPH is an important coenzyme. Which of the following occurs during the Calvin cycle in plants? A. The reduction of NADP+ into NADPH B. The oxidation of NADPH into NADP+ C. The reduction of NADPH into NADP+ D. The oxidation of NADP+ into NADPH E. NADPH is only present in animal cells and therefore does not take part in the Calvin cycle.
