A student claims that NADPH is made when carbon dioxide is reduced during the light reactions. Which response best corrects the claim?
A
NADPH is made when carbon dioxide is oxidized by rubisco inside photosystem II.
B
NADPH is made when oxygen reduces carbon dioxide in the thylakoid lumen.
C
NADPH is made when ATP synthase breaks glucose into NADP+ and phosphate.
D
NADPH is made when NADP+ is reduced by electrons from light-driven electron flow; carbon dioxide reduction occurs later in the Calvin cycle.
