Document Summary
While generating protons that are going to produce atp by atp synthase. Requires 2 photons of light for electron acceptors to pass on e- to nadph. While passing on e-, it gets less and less energetic as it moves down the chain > spontaneous. Second photon of light gives enough energy to pass off e- to ferredoxin. Reduction of co2 in calvin cycle requires more atp than nadph. Cell needs more atp than nadph, and that is why cyclic is more common than non- cyclic. Non-cyclic produced approx. equal amounts of atp and nadph. Nadph able to reduce other molecules in calvin cycle. 2 g3p required to make glucose; 1 extra g3p. Co2 added to rubp by enzyme rubisco; very slow enzyme. Chloroplasts have their own genomes, but they do not code for all of the genes they need. Ssu of rubisco are encoded in the nucleus, translated out into the cytoplasm.
