Diabetes is one of the most common lifestyle disorders in India , which is successfully treated with insulin therapy which radius the blood glucose levels . Which of the following mechanism correctly shown the action of insulin in lowering blood glucose levels ?

Options

A. It stimulates the breakdown of glycogen .
B. It stimulates the process of gluconeogenesis .
C. It acts on adipocytes and hepatocytes and increase cellular glucose uptake and utilization .
D. It reduces glucose uptake and utilization.

Answer

To solve the question regarding the mechanism of insulin in lowering blood glucose levels, we need to analyze the options provided and understand how insulin functions in the body.

### Step-by-Step Solution:

1. **Understanding Insulin's Role**: Insulin is a hormone produced by the beta cells of the pancreas. Its primary function is to lower blood glucose levels.

2. **Mechanism of Action**:
- **Target Cells**: Insulin primarily acts on liver cells (hepatocytes) and fat cells (adipocytes).
- **Glucose Uptake**: Insulin facilitates the uptake of glucose from the bloodstream into these cells. This process is crucial for reducing blood glucose levels.

3. **Analyzing the Options**:
- **Option 1**: Stimulates the breakdown of glycogen - This is incorrect because insulin promotes glycogen synthesis rather than breakdown.
- **Option 2**: Stimulates the process of gluconeogenesis - This is also incorrect as insulin inhibits gluconeogenesis (the production of glucose).
- **Option 3**: Works on adipocytes and hepatocytes, increases the uptake of glucose - This is correct. Insulin enhances glucose uptake in these cells.
- **Option 4**: Decreases the uptake of glucose - This is incorrect as insulin increases glucose uptake.

4. **Conclusion**: The correct mechanism that shows the action of insulin in lowering blood glucose levels is the third option: "works on adipocytes and hepatocytes and increases the uptake of glucose."

### Final Answer:
The correct mechanism of action of insulin in lowering blood glucose levels is: **It works on adipocytes and hepatocytes and increases the uptake of glucose.**
