PHOTOSYNTHESIS - THE LIGHT STAGE
KEY
ATP = Adenosine Tri-Phosphate
ADP = Adenosine Di-Phosphate
P = Phosphate
e- = Electron molecule
H+ = Proton molecule
H20 = Water
02 = Oxegen
NADP = nicotinamide adenine dinucleotide phosphate
NOTE:
NADP+ becomes high energy NADP-
NADP acts as a carrier/taxi for e- and 2H+ to the dark stage of Photosynthesis
PHOTOPHOSPHORALATION
The addition of a phosphate to a molecule
(2e-) + (NADP+) + (2H+)
