Question

Which statement about proteins is true?
A.) Collagen is a structural protein and hemoglobin is a protein involved in the transport of oxygen.

B.) Glycogen is a structural protein and collagen is a protein involved in the transport of oxygen.

C.)Glycogen is a structural protein and hemoglobin is a protein involved in the transport of oxygen.

D.)Hemoglobin is a structural protein and collagen is a protein involved in the transport of oxygen.

Answer 1

A.) Collagen is a structural protein and hemoglobin is a protein involved in the transport of oxygen.

Answer 2

The correct statement is A. Option A is true.  

Structural protein like collagen provides a structural framework and thus support to different cell structures. Hemoglobin is a protein found in red blood cells. It is made up of heme (iron) and globin(globular protein). Heme combines with oxygen to form oxyhemoglobin and transports oxygen to tissues.
