Question

Phycobiliproteins are A. found in purple sulfur bacteria.B. found in cyanobacteria.C. used to gather wavelengths of light that are not well absorbed by chlorophyll.D. are used to reduce hydrogen sulfide.E. found in cyanobacteria AND used to gather wavelengths of light that are not well absorbed by chlorophyll.

Answer 1

The correct answer is option E.

Step-by-step explanation:

The deep-colored, water-soluble proteins, which are mainly found in Rhodophyta and cyanobacteria are known as phycobiliproteins. They captivate the light energy and then pass it to the chlorophyll at the time of photosynthesis.

They are comprised of proteins and are covalently attached through cysteine amino acid chromophores known as phycobilins. Thus, the correct answer is option E.
