1 Energy Storage/Energy consumption Lecture 13: Chp. 6, etc. Summary of Photoreactions to Photophosporylation, note gain of 2 NADPH Becker et al. The World of the Cell Alternatively ATP can be synthesized by cyclic photophosphorylation (PSI), at the expense of NADPH ATP from Photophosphorylation For every 4 e - moving from PSII to PSI, 8 H + (photolysis & from PSII) go to thylakoid lumen. Can generate 2-3 ATP (since 1ATP is synthesized for every 3) Plus for every 4 e - , 2 NADPH can be produced NADPH – higher energy than NADH
