Explanation / Answer

Ans. A. Fibrous protein:

I. Structure is rod-like

II. Keratin

III. Form fibers made of many protein units that are often insoluble in water

IV. Provides structure or support. Fibrous proteins like keratin (nail, hair, hoof, in skin, etc.), muscle fibers (biceps, triceps, body parts and organs, etc.), etc. provide structural support.

B. Globular protein:

            I. Some function as enzyme

            II. Structure is somewhat spherical

            III. Myoglobin

            IV. A significant part of the proteins’ structure may be irregular or unique. Globular proteins, like myoglobin and all protein enzymes may consist of one or more unique regions (often- binding sites and allosteric site, if any). For example, O2-binding site of Myb is unique and different from rest of its structure.

C. Both:

            I. Exhibit primary protein structure

            II. Polymers of amino acid.
