Answer 2

Answer:

Option d) Ossein is the correct option. Ossein is a protein that is present in bones.

Explanation:

Collagen or Type I collagen is the major constituent (approx. 95%) of the organic extracellular matrix that forms about 33% of the bone.

• It is a protein made up of amino acids such as glycine, Arginine, Hydroxyproline, and Proline.
• The organic extracellular matrix is also known as ossein. By separating the inorganic and organic extracellular matrix with hydrochloric acid, ossein can be extracted as demineralized collagen.
• Whereas myosin is a fibrous protein found mainly in muscle cells. Melanin is a skin pigment found in skin, hair, feathers, etc. Hemoglobin is a globin protein found in the red blood corpuscles or RBC.
