Which of the following compound present in the blood is associated with immunity response ?

Options

A. Gamma globulin protein
B. Albumin protein
C. Alpha globulin protein
D. Both (A) and (C)

Answer

To solve the question regarding which compound present in the blood is associated with the immune response, we can follow these steps:

### Step 1: Understand the Options
The options provided are:
- A) Gamma globulin protein
- B) Albumin protein
- C) Alpha globulin protein
- D) Both A and C

### Step 2: Identify the Role of Each Protein
1. **Albumin Protein**: This is the most abundant protein in blood plasma, primarily responsible for maintaining osmotic pressure and transporting substances. It is not directly involved in the immune response.

2. **Alpha Globulin Protein**: These proteins can have various functions, including transport and enzyme activity, but they are not primarily associated with the immune response.

3. **Gamma Globulin Protein**: This group includes immunoglobulins (antibodies), which are crucial for the immune response as they help identify and neutralize pathogens like bacteria and viruses.

### Step 3: Analyze the Information
From the analysis:
- **Gamma globulin proteins** are specifically known for their role in immunity as they consist of antibodies.
- **Albumin** does not play a role in the immune response.
- **Alpha globulin proteins** are not primarily associated with immunity.

### Step 4: Conclusion
Given the information, the compound present in the blood that is associated with the immune response is **Gamma globulin protein**.

### Final Answer
The correct answer is **A) Gamma globulin protein**.
