If the matrix of bone cells contains calcium and phosphorus compounds, then what do we find in the matrix of cartilage?

Correct option is A

• The matrix of cartilage is primarily composed of proteins (such as collagen and elastin) and sugars (such as glycosaminoglycans, including chondroitin sulfate).
• These components provide cartilage with its flexibility, strength, and resilience.
• Unlike bone, which contains calcium and phosphorus compounds, cartilage lacks these minerals and is more flexible and less rigid.

• Cartilage is a type of connective tissue that provides support and flexibility to structures like the ears, nose, and joints.

• The matrix of cartilage contains proteins like collagen (which provides strength) and sugars (such as chondroitin sulfate, which gives cartilage its resilience).

• The absence of calcium in cartilage gives it the flexibility needed for its functions, unlike bones which are hard and mineralized.

• Cartilage is avascular, meaning it does not have blood vessels, and relies on diffusion to obtain nutrients.

Additional Information:

• Proteins and fats: This combination is found in some tissues like adipose tissue (fat storage).

• Phosphorus and sugars:  Phosphorus is more associated with bone matrix.

• Calcium and sugars: This combination is also not found in cartilage, as calcium is mainly found in bones.
