Hill Rxn and photosynthesis

what does light reaction harness energy from

sun and the calvin cycle
energy-storing process where light energy is captured and converted into chemical energy in the form of organic molecules such as glucose

photosynthesis
equation for photosynthesis

6CO2 + 12H2O + sunlight->C6H12O6 + 6O2 + 6H2O
name for the chemical rxns of photosynthesis

light reactions
in light reaction what are the photons absorbed by

photosystem I and II
what happens at the photosystems

light energy excites electrons at the reaction center
What do electrons do in the photosystems
- transfer to primary electron acceptor
- ->travel through electron transport chain
what do electrons eventually do in the photosystems?

reduce NADP+ to NADPH
where do the protons go when ECT pumps them out?

thylakoid lumen
the proton gradient powers the production of ATP through what?

chemiosmosis
what are the NADPH and ATP required for?
- fixing of CO2
- generation of glucose in Calvin Cycle
term for photosystems of the light rxns for the shape during the process

z-scheme
the electrons from water is boosted with energy by?

sunlight
summary of electron movement

H20->PS II->ECT->PSI->ECT->NADPH
who developed the first evidence of electron movement?

Robert Hill in 1937
How did Robert Hill study movement of electrons?
- by adding a artificial electron acceptor to chloroplast
- like DCIP
summary of movement of electrons in the Hill rxn

2H2O->PSII->ECT->DCIP
What plant are we using to observe the chloroplast?

spinach
