Unformatted text preview: Make NADPH out in stroma 2 reduced Fd and NADP+=2oxidized Fd and NADPH 1ATP=1NADPH Cyclic electron flow PSI only Makes ATP No NADPH, No O 2 PS goes to Fd goes to b 6-f goes to Pc and repeats CALVIN CYCLE Makes sugar Depend on products of light reaction 3 phases i. Carbon fixation ii. Reduction iii. Regeneration i. Carbon Fixation Incorp. Of C from CO 2 to organic molecules, multiply everything by 6 to net one molecule 6RuBP + CO 2 = PGA Rubisco Key enzyme= Ribulose bisphosphate carboxylase (RuBisCo) Most abundant protein Most important protein ii. Reduction (increase value of organic molecule) Reduction rearranges a double bond >potential energy Cost: 12 ATP Gives: 2 G3P 12 NADPHs iii. Regeneration of RuBP Costs : 6 ATP Calvin Cycle in total: *6 6 CO 2 + 12 NADPH+18ATP = 1C 6 H 12 O 6 +12NADP + +18 ADP + 18 P i...
