C) a carotenoid

Question

Quizplus · Accepted Answer

Chlorophyll a is the primary photosynthetic pigment found at the reaction center of both photosystem I and II, where it absorbs light energy and transfers it to other pigments and eventually to electron acceptors. While chlorophyll b and carotenoids also play important roles in photosynthesis, they are not located at the reaction center. Carotenoids are found in the antenna complexes, where they absorb excess light energy and protect the plant from photo-oxidative damage. Chlorophyll b is also found in the antenna complexes, where it passes absorbed energy to chlorophyll a.
