Photosystem II produces a proton gradient that drives the synthesis of ATP. Photosystem I yields reducing power in the form of NADPH. Although several groups of bacteria have just one of the two photosystems, the cyanobacteria, algae, and plants have both.C Non-Cyclic Photophosphorylation (Z Scheme) Summary of Photophosphorylation

Location of Photosystem I and II Photosystem II: abundant in the interior, stacked membranes of grana. Photosystem I and ATP synthase: common in the exterior, unstacked membranes. ATP production: Stroma , because the proton gradient established by photosystem II drives protons into the stroma.

Calvin Cycle The Calvin cycle has three phases: 1. Fixation : CO 2 reacts with ribulose bisphosphate ( RuBP ), producing two 3-phosphoglycerate molecules. The attachment of CO 2 to an organic compound is called carbon fixation . 2. Reduction : The 3-phosphoglycerate molecules are phosphorylated by ATP and reduced by NADPH to produce glyceraldehyde 3-phosphate ( G3P ). 3. Regeneration : The remaining G3P is used in reactions that regenerate RuBP.
