Read the given statements and select the correct option.
Statement 1 : Co-factors play a crucial role in the catalytic activity of the enzyme.
Statement 2: Catalytic activity is lost when co-factor is removed from the enzyme.

Options

A. Both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statements 1 and 2 are incorrect.

Answer

To solve the question, we need to analyze both statements regarding the role of cofactors in enzyme activity.

### Step-by-Step Solution:

1. **Understanding Cofactors**:
- Cofactors are non-protein molecules or metallic ions that assist enzymes in their catalytic activity. They are essential for the proper functioning of many enzymes.

2. **Evaluating Statement 1**:
- Statement 1 claims that cofactors play a crucial role in the catalytic activity of enzymes. This is true because cofactors are necessary for the enzyme to perform its function effectively.

3. **Evaluating Statement 2**:
- Statement 2 states that the catalytic activity is lost when the cofactor is removed from the enzyme. This is also true, as the absence of the cofactor means the enzyme may not be able to catalyze reactions, leading to a loss of its activity.

4. **Conclusion**:
- Both statements are correct. Therefore, the correct option is that both Statement 1 and Statement 2 are true.

### Final Answer:
Both Statement 1 and Statement 2 are correct.
