The NADPH/NADP+ cycle is observed in photosynthesis. In the light-dependent reactions, NADP+ becomes NADPH after the light struck the chlorophyll converting light energy to chemical energy. The NADPH produced from the light-dependent cycle is used in the reduction phase of the Calvin Cycle to create G3P, which becomes sugar.
OPTIONS:
X NADP becomes NADPH in the Calvin Cycle.
X The light-independent reaction reduces NADP to NADPH.
X NADPH becomes NADP in the light-dependent reactions.
ANSWER: The Calvin Cycle uses NADPH to form glucose from carbon dioxide.
