Question

Antibodies are secreted by:

• A. T-Cells
• B. B-Cells
• C. α-Cells
• D. β-Cells

Answer 1

The Correct Option is B

Antibody Production: The Role of B-Cells 

This question describes the production of antibodies in the adaptive immune system, focusing on the role of B-cells.

Antibody Production:

• Antibodies (also known as immunoglobulins) are specialized proteins produced by the immune system to recognize and neutralize foreign invaders, such as bacteria, viruses, and toxins.

B-Cells: The Antibody Factories:

• B-Cells (B lymphocytes) are a type of white blood cell (leukocyte) responsible for antibody production.
• B-cells are a critical component of the adaptive immune system, which provides long-lasting immunity to specific pathogens.

Antigen Recognition and Antibody Production:

• Antibodies are produced by B-cells in response to the presence of antigens.

This document describes the role of B-cells in antibody production as part of the adaptive immune response to the presence of antigens.

• Antigens are molecules, typically proteins or polysaccharides, that can be recognized by the immune system. They are often found on the surface of pathogens.
• When a B-cell encounters an antigen that its surface receptor can bind to, the B-cell is activated.

Antibody Production:

• Antibodies are produced by B-cells (also known as B lymphocytes).
