The only thing my biology teacher told us about the NADP (in photosynthesis light dependent reaction) is that it's a bus driver. Why is it a bus driver? Is it cos it collects the H+ ion into the light independent reaction (NADPH) then "drops" it off and returns back to the light dependent reaction?

If there is a tutor here who can help you with this question, I'm sure he/she will add a response.
