NADP+ functions in photosynthesis while NADPH functions in cellular respiration.
NADP+ functions in photosynthesis while NADPH functions in cellular respiration.

Answer 1

The correct response is:

NADP+ does not have an electron attached whereas NADPH does have an electron attached and is therefore carrying energy.

NADP+ (Nicotinamide adenine dinucleotide phosphate) is the oxidized form, while NADPH is the reduced form, which carries electrons (and therefore energy) necessary for various biochemical reactions, particularly in photosynthesis.
