Assertion : Insulin is a glubular protein.
Reason : Gloubular proteins are water soluble.

Options

A. If both assertion and reason are true , and is the true explanation of the assertion.
B. If both assertion and reason are true, but reason is not the true explanation of the assertion.
C. If asseration is true , but reason is false.
D. If both assertion and reason are false.

Answer

To analyze the given assertion and reason, we will break down the information step by step.

### Step 1: Understand the Assertion
The assertion states that "Insulin is a globular protein."
- **Explanation**: Insulin is indeed classified as a globular protein. Globular proteins are typically spherical in shape and are soluble in water. They play various roles in biological processes, including enzyme activity and regulation of physiological functions.

### Step 2: Understand the Reason
The reason states that "Globular proteins are water soluble."
- **Explanation**: Globular proteins are characterized by their solubility in water due to their hydrophilic (water-attracting) side chains on their amino acids. This solubility allows them to function effectively in biological systems, where they often act as enzymes, hormones, and other functional molecules.

### Step 3: Analyze the Relationship Between Assertion and Reason
Now, we need to determine if both the assertion and reason are true and if the reason correctly explains the assertion.
- Both statements are true: Insulin is a globular protein, and globular proteins are indeed water-soluble.
- The reason provides a correct explanation for the assertion because the solubility of insulin as a globular protein is a characteristic feature of this type of protein.

### Conclusion
Since both the assertion and reason are true, and the reason explains the assertion, the answer is that both statements are correct and the reason is a true explanation of the assertion.

### Final Answer
Both the assertion and reason are true, and the reason is a correct explanation of the assertion.
