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?

|
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.
