The hormone that can increase the value rate of breakdown of glycogen ,the volume of blood in vessels and rate of heartbeat is

Options

A. insulin
B. glucagon
C. adrenaline.
D. FSH.

Answer

To solve the question about which hormone can increase the rate of breakdown of glycogen, the volume of blood in vessels, and the rate of heartbeat, we can follow these steps:

### Step 1: Understand the Functions of Each Hormone
- **Insulin**: Secreted by the pancreas, it lowers blood sugar levels by promoting the uptake of glucose and the storage of glycogen.
- **Glucagon**: Also secreted by the pancreas, it raises blood sugar levels by promoting the breakdown of glycogen into glucose.
- **Adrenaline (Epinephrine)**: Produced by the adrenal glands, it increases heart rate, blood pressure, and the breakdown of glycogen into glucose, especially during stress or physical activity.
- **FSH (Follicle Stimulating Hormone)**: Involved in reproductive processes, stimulating the growth of ovarian follicles.

### Step 2: Analyze the Question
The question asks for a hormone that:
1. Increases the breakdown of glycogen.
2. Increases the volume of blood in vessels.
3. Increases the rate of heartbeat.

### Step 3: Eliminate Incorrect Options
- **Insulin**: Lowers blood sugar and promotes glycogen storage, so it does not fit the criteria.
- **Glucagon**: While it increases blood sugar by breaking down glycogen, it does not directly increase heart rate or blood volume.
- **FSH**: Not related to glycogen breakdown or heart rate; it is focused on reproductive functions.

### Step 4: Identify the Correct Option
- **Adrenaline**: This hormone fits all the criteria. It stimulates the breakdown of glycogen, increases heart rate, and raises blood pressure, which in turn increases the volume of blood in vessels.

### Conclusion
The hormone that can increase the rate of breakdown of glycogen, the volume of blood in vessels, and the rate of heartbeat is **Adrenaline**.
