Assertion : GLUT -4 is one of the essential protein for bioenergetics
of the cell
Reason : GLUT-4 enables glucose transport in to cell

Options

A. If both assertion & Reason are ture & the Reason is a correct explanation of the Assertion
B. If both Assertion & Reason ar True but Reason is not a correct explantation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "GLUT-4 is one of the essential proteins for bioenergetics of the cell."
- GLUT-4 is a glucose transporter protein that plays a crucial role in cellular metabolism and energy production.

2. **Understanding the Reason**:
- The reason states that "GLUT-4 enables glucose transport into the cell."
- GLUT-4 facilitates the uptake of glucose from the bloodstream into cells, particularly in muscle and fat tissues, which is essential for energy production.

3. **Evaluating the Truth of the Assertion**:
- Since GLUT-4 is indeed vital for the transport of glucose, which is a primary energy source for cells, the assertion is true.

4. **Evaluating the Truth of the Reason**:
- The reason accurately describes the function of GLUT-4, confirming that it enables glucose transport into the cell, making this statement true as well.

5. **Determining the Relationship**:
- Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the reason is a correct expression of the assertion.

6. **Choosing the Correct Option**:
- Based on the evaluation, the correct answer is that both the assertion and reason are true, and the reason is the correct expression of the assertion.

### Final Answer:
The correct option is: **Both assertion and reason are true, and reason is the correct expression of assertion.**
