What is the main role of the light-harvesting (antenna) complexes in Photosystems I and II?
a) split water and release oxygen into the inter-thylakoid membrane space
b) absorb light energy (photons) and transfer the energy to the reaction-center molecules P680 and P700
c) donate electrons to molecules in one of two electron transport chains
d) pump protons (H+) into the inner thylakoid space to make ATP via chemiosmosis
