Section 1

Question Answer
what path do electrons follow in linear electron transportphotosystem 2(water is split) to plastoquinone to cytochrome complex to plastocyanin, to photosystem 1 to ferrodoxin the NADP+ reductase to NADP+
3 ways H+ gradient is created lysis of water, transportation from storm to lumen via plastoquinone and using H+ for NADP+ reduction on storm side
what is produced in linear electron transport1 NADPH
what is required to overcome energy difference between NADPH and H2O2 photons of light
memorize

Section 2

Question Answer
what path do cyclic electrons followelectrons cycle around PQ, cytochrome complex, photosystem 1 and ferrodoxin WITHOUT involving photosystem 2
what does the cyclic electron transport accomplishcreates ATP without reduction of NADP+ to NADPH
why is this process important because more ATP than NADPH are needed for the Calvin cycle to continue
how is ATP synthesized proton-motive force across the thylakoid causes chemiosmotic synthesis through ATP synthase
What is the difference between photophosphorylation and oxidative phosphorylation photophosphorylation uses light as energy to generate ATP
memorize

Section 3

Question Answer
what are the products of light dependant reactions used forlight independent reactions
what is the main enzyme for light independent reactionsrubisco, most abundant protein on earth
where is this enzyme formedportions in chloroplasts, others in nucleus, evidence of gene transfer
What are the 3 stages of the Calvin cyclefixation of CO2, reduction of 3-phosphoglycerate to G3P, regeneration of RuBP from G3P
how many more ATP are needed than NADPH3
