The light-harvesting complex (LHC) and reaction centre of a photosystem differ in that
AAntenna pigments do chemistry while reaction centre does not
BBoth perform identical chemistry on photons
CAntenna pigments contain only carotenoids alone
DAntenna pigments funnel energy to a special chl a pair
Answer & Solution
Correct answer: D. Antenna pigments funnel energy to a special chl a pair
LHC antenna = hundreds of pigments (chl a, chl b, xanthophyll, carotenoids) that absorb photons and transfer energy by resonance to a single special chlorophyll a pair (reaction centre, P680 or P700) where photochemistry occurs.
