a) A-peptide
c) D-peptide
b) B-peptide
d) -peptide

Answer 1

Answer:

The forth option is not clear.

Answer is C-peptide

Answer 2

The complete question is-

The part of Human insulin which is removed during the maturation of pro-insulin is

a) A-peptide

c) D-peptide

b) B-peptide

d) C-peptide

Answer-

The part of Human insulin which is removed during the maturation of proinsulin is C-peptide (Option d)

• The mature insulin is formed by the modifications in the pro-insulin.
• Pro-insulin is the precursor molecule and contains three peptide chains- A, B, and C. The C-peptide is called the extra peptide.
• During processing (maturation) of this hormone, C-peptide gets removed and the A and B chains are linked by di-sulphide bonds.
•  This is the major difference between pro-insulin and insulin.
