Document Summary

Both cellular respiration and photosynthesis occur at the same time in a plant- cr in the. Root system and p in the upper part. Net photosynthesis: the balance between how much o2 is being used or given up or co2 being used or given up. This is an incorrect diagram but it explains the. Process properly (showing psii in an unstacked area) *spinach- 2/3 (65%) of the chloroplasts are psii (twice as many copies of psii than psi) 1/3 (35%) of the chloroplasts are psi. Non-stacked- outside part (psi, psii inactive, atp synthase, cytochrome system) Stacked- lumen has folded over itself building a grana structure (psii is active, cytochrome system) Bassham-benson-calvin cycle: normally concurs with light reactions, uses atp & nadph, three phases, fixation of co2 (catalyzed by rubisco, reduction, regeneration of the co2 acceptor so it can accept it at the beginning of the cycle (ribulose-1,5-biphosphate rubp) Co2 + rubp 3-phosphoglycerate (pga) .
