Statement -1: `alpha`-Keratin is a structural protein
Statement -2: It is globular protein.

Options

A. Statement 1 is true, statement-2 is true , statmenent -2 is a correct explanation for statement -1
B. Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 1
C. Statement 1 is true, statement 2 is false
D. Statement 1 is false, statement 2 is true

Explanation

To analyze the statements provided in the question, we will evaluate each statement regarding alpha-Keratin.

### Step 1: Understand the nature of alpha-Keratin
Alpha-Keratin is a type of protein that is primarily found in the structural components of various organisms. It is a key component of hair, nails, and the outer layer of skin.

**Hint:** Remember that proteins can be classified into two main categories: fibrous and globular.

### Step 2: Classify alpha-Keratin
Alpha-Keratin is classified as a fibrous protein. Fibrous proteins are typically elongated and have structural roles, providing support and strength to cells and tissues.

**Hint:** Think about where you find keratin in the body and its function.

### Step 3: Evaluate Statement 1
Statement 1 claims that "alpha-Keratin is a structural protein." This statement is true because alpha-Keratin indeed serves a structural role in the body, contributing to the strength and resilience of hair, nails, and skin.

**Hint:** Consider the role of proteins in the structure of biological tissues.

### Step 4: Evaluate Statement 2
Statement 2 claims that "it is a globular protein." This statement is false. Globular proteins are typically spherical and often function as enzymes or hormones, whereas alpha-Keratin is fibrous and does not fit this description.

**Hint:** Recall the characteristics that differentiate fibrous proteins from globular proteins.

### Conclusion
Based on the evaluations:
- Statement 1 is true: alpha-Keratin is a structural protein.
- Statement 2 is false: alpha-Keratin is not a globular protein; it is a fibrous protein.

Thus, the correct answer is that Statement 1 is true and Statement 2 is false.

### Final Answer
- Statement 1: True
- Statement 2: False
