NEET Chemistry Proteins Match the Following Question
Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Primary structure | (i) Insulin |
| (b) Globular proteins | (ii) Sequence of amino acids |
| (c) Zwitter ion | (iii) Amphoteric behaviour |
| (d) Optical activity | (iv) Asymmetric carbon |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-iv, b-iii, c-i, d-ii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The primary structure of proteins refers to the specific sequence of amino acids (a-ii). Globular proteins like insulin are water-soluble and have a spherical shape (b-i). Zwitter ions exhibit amphoteric behaviour due to their dual charge (c-iii), and optical activity is present in amino acids with an asymmetric carbon atom (d-iv).
