Which of the Following is True Regarding Light-Harvesting Complexes in Plant

Question

Which of the following is true regarding light-harvesting complexes in plant chloroplasts?
A) They contain chlorophyll and other pigments.
B) They are found in both photosystem I and photosystem II.
C) They can protect the cell by preventing the generation of reactive oxygen species.
D) They cannot carry out charge separation.
E) All of the above.

Accepted Answer

Light-harvesting antenna complexes, found in both photosystems, contain chlorophyll molecules as well as orange carotenoid pigments. They help prevent the formation of harmful oxygen radicals. They collect the energy of a sufficient number of photons for photosynthesis, and pass the energy to the special pair in the reaction center, where the charge-separation step takes place.
