Insulin promotes :

Options

A. Glycogenesis
B. Glucosuria
C. Glycogenolysis
D. Gluconeogenesis

Answer

**Step-by-Step Solution:**

1. **Understanding Insulin**: Insulin is a hormone produced by the beta cells of the islets of Langerhans in the pancreas. It plays a crucial role in regulating blood glucose levels.

2. **Identifying the Function of Insulin**: The primary function of insulin is to lower blood glucose levels. It does this by facilitating the uptake of glucose into cells and promoting the storage of glucose in the form of glycogen.

3. **Evaluating the Options**:
- **Option 1: Glycogenesis**: This is the process of converting glucose into glycogen for storage. Insulin promotes glycogenesis when blood glucose levels are high.
- **Option 2: Glucosuria**: This refers to the presence of glucose in urine, which occurs when blood glucose levels are excessively high and the kidneys cannot reabsorb all the glucose. This is not promoted by insulin.
- **Option 3: Glycogenolysis**: This is the breakdown of glycogen back into glucose. Insulin does not promote this process; rather, it inhibits it.
- **Option 4: Gluconeogenesis**: This is the synthesis of glucose from non-carbohydrate sources. Insulin does not promote gluconeogenesis; it actually inhibits it when glucose levels are adequate.

4. **Conclusion**: Based on the evaluation, the correct answer is **Option 1: Glycogenesis**, as insulin promotes the synthesis of glycogen from glucose.
