Question

Select the odd one.

• A. Carotenoid
• B. Glucose
• C. Vinblastin
• D. Codeine

Answer 1

The correct option is B Glucose

Those metabolites which have identifiable functions and play an important role in normal physiological processes of living organisms are known as primary metabolites.

Secondary metabolites are compounds produced by an organism but not directly involved in growth and development.

Carotenoid, vinblastin and codeine are all secondary metabolites whereas glucose is a primary metabolite.
