Chlorophyll b
A) is best at absorbing the energy of green light.
B) is best at absorbing the energy of blue-violet and red light, just like chlorophyll a.
C) passes absorbed energy to chlorophyll a.
D) catalyzes the incorporation of carbon atoms into RuBP.

Question

Quizplus · Accepted Answer

Chlorophyll b absorbs light with wavelengths slightly different from those absorbed by chlorophyll a, and passes the energy it absorbs to chlorophyll a, which then uses it for photosynthesis. Chlorophyll b is not as efficient as chlorophyll a at absorbing energy from light, so it serves a supporting role in photosynthesis. Chlorophyll b is not involved in the incorporation of carbon atoms into RuBP, nor is it best at absorbing the energy of green light.
