Injection of insulin to human leads to increased:

Options

A. Glucose level of blood
B. Glucose level of wine
C. Glucose level of cells
D. None of these

Answer

To answer the question "Injection of insulin to human leads to increased:", we need to analyze the role of insulin in the human body.

### Step-by-Step Solution:

1. **Understanding Insulin**: Insulin is a hormone produced by the beta cells of the pancreas. Its primary function is to regulate glucose levels in the blood.

2. **Function of Insulin**: When insulin is injected, it facilitates the uptake of glucose by various cells in the body, including liver cells, muscle cells, and adipose (fat) tissue.

3. **Effect on Blood Glucose Levels**: Insulin lowers the blood glucose level by promoting the uptake of glucose into cells. Therefore, when insulin is injected, the glucose level in the blood decreases rather than increases.

4. **Effect on Cellular Glucose Levels**: As cells take up more glucose due to the action of insulin, the glucose levels inside these cells increase. This is because insulin encourages cells to absorb glucose from the bloodstream.

5. **Conclusion**: Based on the above points, the injection of insulin leads to an increase in glucose levels within the cells, while the blood glucose level decreases.

### Final Answer:
The injection of insulin leads to increased glucose levels in the cells.
