Chlorophyll a, chlorophyll b, and carotenoids. They either absorb or reflect wavelengths
note;
absorption spectrum; amount of each wavelength absorbed
action spectrum; effectiveness of a wavelength
main purpose to absorb n transfer light energy (transfers electrons)
found in thylakoid membranes
depends on pigments inside the thylakoid
there is 2; Photosystem I, photosystem II.
photosystem II happens before photosystem I
they act like “light gathering antenna”
happens at anytime, after NADPH + ATP is created. Then, the calvin-benson cycle takes place.
Occurs in the stroma.
each turn of calvin cycle “fixes” carbon,
3 turns makes PGAL/G3P, fixing 3 CO2’s
6 turns makes 1 glucose
carbon is fixed to a molecule
glucose is formed
e-’s are lost and gained in the form of hydrogen
water DONATES e-’s n is oxidized. WATER SPLITS AND OXYGEN IS PRODUCED
carbon accepts e-’s n REDUCES to form sugar
