PSI and PSII.
|
|
|
What lies between PSI and PSII
|
The cytochrome B6f complex.
|
|
|
What does the photosynthetic electron transport system do?
|
Raises electrons to higher energy levels needed to generate NADPH.
|
|
|
What does most of the chlorophyll in photosystems function as?
|
Antenna chlorophyll.
|
|
|
What two things absorb photons of light?
|
Chlorophyll and accessory pigments.
|
|
|
give an example of an accessory pigment that absorbs photons of light.
|
carotenoids.
|
|
|
how is energy transferred to the chlorophyll reaction centre?
|
via resonance.
|
|
|
what kind of chlorophyll is found in PSII? PSI?
|
PSII is p680, PSI is p700.
|
|
|
what does p680 and p700 correspond to?
|
the wavelength at which the chlorophyll in each reaction centre maximally absorbs light.
|

What does the core complex contain?
|
the reaction centre.
|
|
|
what happens in the reaction centre of the core complex.
|
the primary charge separation.
|
|
|
what is the core complex surround by?
|
The antenna.
|
|
|
what do the antenna contain?
|
a light harvesting complex.
|
|
|
what is the light harvesting complex made of?
|
three light harvesting complex polypeptides and associated pigments embedded in the membrane.
|
|
|
how many chl and carotenoid molecules do spinach chloroplasts contain?
|
200 chl and 50 carotenoid pigments.
|
