The correct Answer is:
To solve the question regarding the production and functions of the glycoprotein represented as H2L2, we can follow these steps: ### Step 1: Identify H2L2 - The notation H2L2 refers to the structure of antibodies, which are glycoproteins composed of two heavy chains (H) and two light chains (L). ### Step 2: Understand the Production of Antibodies - Antibodies are produced by a specific type of white blood cell known as B lymphocytes. When B lymphocytes are activated, they differentiate into plasma cells, which are responsible for the secretion of antibodies. ### Step 3: Determine the Nature of Antibodies - Antibodies are classified as glycoproteins due to the presence of carbohydrate moieties attached to the protein structure. This glycoprotein nature is crucial for their function in the immune response. ### Step 4: Identify the Function of Antibodies - One of the key functions of antibodies is opsonization, which enhances the ability of phagocytes to engulf and destroy pathogens. This is an important aspect of the immune response. ### Step 5: Choose the Correct Option - Based on the information gathered, the correct option related to the production and function of the glycoprotein H2L2 (antibody) is the one that mentions plasma cells and opsonization. ### Final Answer - The correct answer is **Option 4**, which states that plasma cells are involved in the production of antibodies and that their function includes opsonization. ---
