ATP and NADPH (made in the light stage) in Calvin Cycle -
1. A five-carbon sugar molecule called ribulose bisphosphate, or RuBP, is the acceptor that binds CO2 dissolved in the stroma. This process, called CO2 fixation, is catalyzed by the enzyme RuBP carboxylase, forming an unstable six-carbon molecule. This molecule quickly breaks down to give two molecules of the three-carbon 3-phosphoglycerate (3PG), also called phosphoglyceric acid (PGA).
2. The two 3PG molecules are converted into glyceraldehyde 3-phosphate (G3P, a.k.a. phosphoglyceraldehyde, PGAL) molecules, a three-carbon sugar phosphate, by adding a high-energy phosphate group from ATP, then breaking the phosphate bond and adding hydrogen from NADPH + H+.
3. Three turns of the cycle, using three molecules of CO2, produces six molecules of G3P. However, only one of the six molecules exits the cycle as an output, while the remaining five enter a complex process that regenerates more RuBP, using ATP) to continue the cycle. Two molecules of G3P, produced by a total of six turns of the cycle, combine to form one molecule of glucose

i will help w/ the Calvin cycle, as i'm not too familiar with photosystem i and II. interior the TCA cycle (Calvin), Carbon Di Oxide, water and ATP are produced as by things. which potential, CO2, H20 and ATP are produced. O2 is used to gasoline the cardio or Calvin cycle, NADP+ and NADPH are enzymatic co-enzymes that help with the circulate of electrons interior the electron delivery chain, and ADP is phosphorylation (a phosphate is extra) to create ATP.
