Hormone that maintains the blood glucose level within the limit is

Options

A. Thyroxine
B. Insulin
C. Testesterone
D. Epinephrine

Answer

To answer the question regarding which hormone maintains blood glucose levels within limits, we can follow these steps:

### Step 1: Understand the Question
The question asks for a hormone that regulates blood glucose levels. This is important for maintaining homeostasis in the body.

### Step 2: Identify the Options
The options provided are:
1. Thyroxine
2. Insulin
3. Testosterone
4. Epinephrine

### Step 3: Analyze Each Option
- **Thyroxine**: This hormone is produced by the thyroid gland and primarily regulates metabolism but does not directly control blood glucose levels.

- **Insulin**: This is a peptide hormone secreted by the pancreas. Its primary function is to lower blood glucose levels by facilitating the uptake of glucose into cells and promoting its storage as glycogen in the liver and muscles.

- **Testosterone**: This is a steroid hormone that plays a role in the development of male reproductive tissues and secondary sexual characteristics, but it does not have a direct role in regulating blood glucose levels.

- **Epinephrine**: Also known as adrenaline, this hormone is produced by the adrenal glands and is involved in the fight-or-flight response. It can increase blood glucose levels by promoting glycogen breakdown but does not maintain glucose levels within limits.

### Step 4: Conclude the Correct Answer
Based on the analysis, the hormone that maintains blood glucose levels within limits is **Insulin**. Therefore, the correct option is **Option 2: Insulin**.

### Final Answer
The hormone that maintains the blood glucose level within the limit is **Insulin**.
