Intercellular matrix is "solid" while cartilage is pliable due to the presence of

Options

A. Chondroitin salt
B. Ammonium salt
C. Magnesium salt
D. Metalloid

Answer

To answer the question, "Intercellular matrix is 'solid' while cartilage is pliable due to the presence of," we need to analyze the options provided and understand the composition of cartilage.

### Step-by-Step Solution:

1. **Understanding Cartilage Composition**:
- Cartilage is a type of connective tissue that is known for its pliability and flexibility. This property is primarily due to its unique extracellular matrix.

2. **Identifying Key Components of Cartilage**:
- The extracellular matrix of cartilage is rich in specific substances. The main components include:
- **Collagen fibers**: These provide structural support.
- **Proteoglycans**: These are large molecules that attract water and provide cushioning.
- **Elastin fibers**: These contribute to the elasticity of the cartilage.

3. **Analyzing the Options**:
- The options provided are:
- A) Chondroitin salt
- B) Ammonium salt
- C) Magnesium salt
- D) Metalloid
- Among these, **chondroitin sulfate** is a type of proteoglycan that is found in the extracellular matrix of cartilage. It plays a significant role in maintaining cartilage structure and function.

4. **Conclusion**:
- Given that chondroitin sulfate is a major component of the cartilage matrix that contributes to its pliability, the correct answer to the question is **A) Chondroitin salt**.

### Final Answer:
The intercellular matrix is solid while cartilage is pliable due to the presence of **Chondroitin salt**.
