Question

Match the following column I and column II and choose the correct option.

	Column-I		Column-II
a.	Abrin	(i)	Succinate dehydrogenase inhibitor
b.	Oxaloacetate	(ii)	Polymer of N-acetylglucosamine
c.	Exoskeleton of arthropods	(iii)	Possess peptide bonds
d.	GLUT-4	(iv)	Toxin, secondary metabolite

• A. a - iv, b - iii, c - ii, d - i
• B. a - iii, b - ii, c - i, d - iv
• C. a - iv, b - i, c - ii, d - iii
• D. a - i, b - iii, c - iv, d - ii

Answer 1

The correct option is C a - iv, b - i, c - ii, d - iii

Abrin is a toxin, a secondary metabolite. Malonate and oxaloacetate are competitive inhibitor of succinic dehydrogenase.
Exoskeleton of arthropods is made up of chitin which is a homopolymer of NAG. GLUT-4 is a proteinaceous receptor molecules for the transport of glucose into cells.
