What connective tissue component is unique to cartilage?
A) matrix hardened by calcium and phosphorus
B) extracellular matrix
C) fibroblasts
D) elastin
E) rubbery, compression-resistant proteoglycans
Proteoglycans
Large molecules found in the extracellular matrix of animal tissue, consisting of a core protein and one or more covalently attached glycosaminoglycan (GAG) chains, involved in maintaining the structural integrity of tissues.
Cartilage
A flexible, strong tissue found in joints and other parts of the body, providing support and cushioning.
Elastin
A highly elastic protein in connective tissue that allows many tissues in the body to resume their shape after stretching or contracting.

Final Answer :
E
Explanation :
The rubbery, compression-resistant proteoglycans are a unique connective tissue component of cartilage. The extracellular matrix and fibroblasts are also present in other types of connective tissues, while the matrix hardened by calcium and phosphorus is specific to bone tissue. Elastin is present in certain types of connective tissue such as elastic cartilage and blood vessels, but is not unique to cartilage.
