NADP

(Science: chemical) nicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (nmn) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidised (NADP_) and reduced (nADPH).

Chemical name: Adenosine 5'-(trihydrogen diphosphate), 2'-(dihydrogen phosphate), P'-5'-ester with 3-(aminocarbonyl)-1-beta-D-ribofuranosylpyridinium, inner salt A coenzyme similar to NAD and present in most living cells but serves as a reductant in different metabolic processes.Shorthand version of nicotinamide adenine dinucleotide, a [[ coenzyme that can accept hydrogen.

2. Yes, it is the electron from photosystem I(P700) that is used to reduce NADP+. 3. There is nothing different about the chl a molecules. Chl a is chl a, and they all have the same structure. However, because they are surrounded by different proteins, their ...

... plastoquinone. Those electrons travel down through the cytochrome chain to plastocianin to eventually rich P700. P700 can donate electrons to NADP+, converting it to NADPH. The protons in this reaction are taken up from the solution, where they are readily available. Here is a diagram. http://www.com.univ-mrs.fr/IRD/atollpol/glossaire/images/ps3.jpg ...

photosynthesis

... The excitation is passes along to a molecule of p680 chlorophyll in the photosynthetic unit C. The p680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+ D. The electron vacancies in p680 are filled by electrons derived from water. E. The splitting of water yields ...

Does oxygen production in photosynthesis require CO2?

Actually you will only be able to generate oxygen for a very, very little while. This is because the light reactions require NADP+ in order to proceed. Normally the Calvin-Bensen cycle consumes the NADPH2 produced in the light reaction and produces NADP+. But if you were to turn off ...
