Photosynthesis

sunlight - glucose (plants)- ATP (us) - Energy lost as heat

Stroma- Fluid of chloroplast
~thylakoid structure- entire system
~granham- stacks of thylakoid membrane
~chloroplast membrane- double lipid bilayer
stroma: H2O dissolved oxygen

light comes in, strikes thylakoid, water is bio

NADP+ will only bond with H+ if H+ has 2 energized electrons = NADPH

chlorophyll a
chlorophyll b
- the thylakoid structure has molecules embedded within them. These molecules contain chlorophyll a/b.
Sunlight comes in and strikes chlorophyll pigment, then it overcharges the chlorophyll. Then it releases electron through electron transport system, which generates ATP. It then returns to chlorophyll. Energy bounces off random chlorophyll loosing energy each time.

Phasilitated diffusion- allow ions to get through membrane by putting a hole in it.
