The function of insulin hormone is :-

Options

A. To release glucose from liver cells and glycogenolysis promotion
B. To increase cellular glucose uptake and consumption
C. To increase blood sugar level
D. To increase lipolysis

Answer

### Step-by-Step Solution:

1. **Understanding Insulin**: Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels.

2. **Function of Insulin**: The primary function of insulin is to facilitate the uptake of glucose by cells, particularly muscle and fat cells. This process helps lower blood sugar levels.

3. **Glucose Storage**: Insulin promotes the conversion of glucose into glycogen for storage in the liver and muscle tissues. This process is known as glycogenesis, not glycogenolysis.

4. **Opposition to Glucagon**: Insulin acts in opposition to glucagon, another hormone that raises blood glucose levels. While glucagon promotes the release of glucose into the bloodstream, insulin works to decrease blood glucose levels.

5. **Effects on Lipid Metabolism**: Insulin also influences lipid metabolism by promoting the storage of fats and inhibiting lipolysis (the breakdown of fats).

6. **Summary of Functions**: In summary, the functions of insulin include:
- Increasing cellular uptake of glucose.
- Promoting the conversion of glucose to glycogen (glycogenesis).
- Lowering blood glucose levels.
- Inhibiting the breakdown of fats.

### Final Answer:
The function of insulin hormone is to increase cellular glucose uptake, promote the conversion of glucose to glycogen, and lower blood glucose levels.
