Which of the following is a difference between chlorophyll a and chlorophyll b?
A) Chlorophyll a is a pigment, and chlorophyll b is the enzyme that transfers excited electrons from chlorophyll a to electron carriers of the thylakoid membrane.
B) Chlorophyll a absorbs yellow light, and chlorophyll b absorbs green.
C) Chlorophyll a contains magnesium in its ring structure, whereas chlorophyll b contains iron.

Question

Quizplus · Accepted Answer

Chlorophyll a and b differ in their absorbance spectra, meaning they absorb light energy at slightly different wavelengths. Chlorophyll a absorbs best in the blue and red parts of the spectrum, whereas chlorophyll b absorbs best in the blue and green parts of the spectrum. This difference in absorbance spectra allows for more efficient light capture and utilization by photosynthetic organisms.
