Question

$\begin{array}{cc}\text{Column - I}& \text{Column - II}\\ \text{(i) Keratin}& \text{(A) Aldohexose}\\ \text{(ii) Glucose}& \text{(B) Fibrous protien}\\ \text{(iii) Fructose}& \text{(C) Globular protein}\\ \text{(iv) Insulin}& \text{(D) Ketohexose}\end{array}$
Which of the following is the best matched option?

• A. i-C, ii- A, iii- D, iv-B
• B. i-B, ii- A, iii- D, iv-C
• C. i-B, ii- D, iii- A, iv-C
• D. i-C, ii- D, iii- A, iv-B

Answer 1

The correct option is B i-B, ii- A, iii- D, iv-C

Keratin is a fibrous protein.
Insulin is a globular protein.
Glucose has both an aldehyde group and six carbon, so it is an aldohexose.
Fructose contains both a keto group and six carbon, so it is a ketohexose.
