Chlorophyll and light harvesting complexes

Question 1

Effect of having different pigment environments

Answer 1

Broadens spectral cross section
Creates directionality in energy flow
Having different pigments that each absorb a type of light (eg blue) E
Unique pigment environments further increases the wavelengths of light that can be absorbed
Therefor increasing efficiency

Question 2

Which chlorophyll distance from RC have higher energy excited state?

Answer 2

Chlorophylls further from reaction center have higher energy excited state
