I have gone through various sites and some say there is NADPH2 and some say there is no NADPH2 there's only NADP+ ...WHich is the correct view....Please dont mark this answer as duplicates since I have asked a similar question related to photosynthesis in the past but there too I have not received any satisfactory answer bythe community .
I answered this implicitly in a comment to my answer to: Light and Dark Reaction of photosynthesis?. Anyway:
The nicotinamide portion of NADP that undergoes oxidation and reduction is exactly the same as in NAD. The changes undergone are:
The error either comes from confusion with the other redox cofactor, FAD / FADH2, or the fact that two electrons are involved in the reduction of NADP:
NADP+ + H+ + 2e → NADPH
