Question

Fibrous and globular proteins are classified on the basis of ______ structure.

(a) primary

(b) secondary

(c) tertiary

(d) quaternary

The question was posed to me by my school principal while I was bunking the class.

I need to ask this question from Biomolecules in chapter Biomolecules of Chemistry – Class 12

Answer 1

The correct choice is (c) tertiary

The explanation is: Tertiary structure represents the overall folding of the polypeptide chains or the further folding of secondary structures. It gives rise to two major molecular shapes, i.e., fibrous and globular.
