Insuline increases

Options

A. breakdown of fats
B. breakdown of protein
C. breakdown of glycogen in liver
D. uptake of glucose by its terget tissues

Answer

**Step-by-Step Solution:**

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

2. **Function of Insulin**: The primary function of insulin is to lower blood sugar levels when they are elevated. This occurs after meals when glucose from food enters the bloodstream.

3. **Mechanism of Action**: When blood sugar levels rise, the pancreas secretes insulin. Insulin facilitates the uptake of glucose by various tissues, especially muscle and fat cells, allowing them to use glucose for energy or store it for future use.

4. **Conversion of Glucose**: Insulin promotes the conversion of excess glucose into glycogen, which is stored in the liver and muscles. This process is known as glycogenesis.

5. **Comparison with Glucagon**: In contrast, when blood sugar levels drop (such as during fasting), another hormone called glucagon is secreted, which stimulates the breakdown of glycogen back into glucose (glycogenolysis) to increase blood sugar levels.

6. **Conclusion**: Therefore, the correct answer to the question "Insulin increases" is the "uptake of glucose by its target tissues."

**Final Answer**: The correct option is the uptake of glucose by its target tissues.
