Question

Which of the following statements about the NADPH/NADP cycle is true?0 000NADP becomes NADPH in the Calvin Cycle.The light-independent reactions reduces NADP to NADPH.The Calvin Cycle uses NADPH to form glucose from carbon dioxide.NADPH becomes NADP in the light-dependent reactions,

Answer 1

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.
