WebDec 10, 2024 · The key difference between chlorophyll and carotenoids is that the chlorophyll is a family of green colour pigments primarily used for photosynthesis in photosynthetic organisms while the carotenoids are a group of yellow to red colour pigments including carotenes and xanthophylls that are accessory pigments. The pigment is a … WebThe chlorophyll molecule transfers the excited electron from the first singlet state to an electron acceptor and a pos-the excited electron is bound less strongly to the chromophore molecule than in the ground state. When the chlorophyll molecule returns to the ground state, the free energy derived from this process is conserved for chemical work.
