Red to orange pigments are_____________?
Correct answer: A. Carotenes
- A. Carotenes
- B. Carotenoids
- C. Xanthophylls
- D. Chlorophyll
Explanation
Carotenes are carotenoid pigments that commonly produce red, orange or orange-yellow colours and contain only carbon and hydrogen. Xanthophylls are oxygen-containing carotenoids and are generally yellow, so c is the likely choice when all carotenoid pigments are treated as identical.

About Conjugated Molecules
Conjugated molecules contain a non-protein component attached to a protein portion, giving the molecule properties that a simple protein lacks. The content includes glycoproteins, lipoproteins, phosphoproteins, nucleoproteins, chromoproteins and metalloproteins, with attention to their prosthetic groups and roles in transport, protection, catalysis and cellular structure.
