Answers (1)


Collagen and elastic fibres make up the dense, gel-like substance known as cartilage. It contains chondroitin sulphates, a type of polysaccharide derivative, which combines with the protein in the ground substance to produce proteoglycan. The cells known as chondroblasts, which develop into chondrocytes and are situated in tiny spaces known as lacuna, generate the matrix. N-acetylgalactosamine and glucuronic acid are chains of sugars that alternately make up chondroitin sulphate, a sulfated glycosaminoglycan (GAG). It often appears as a proteoglycan linked to proteins.

Option  2 is the correct answer.
