Antibodies are made of which of the following types of substances?
- A. Fat
- B. Protein
- C. Sugar
- D. Carbohydrates CARE OF PATIENTS WITH IMMUNE DISORDERS
Correct Answer: B
Rationale: Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to the presence of pathogens like bacteria, viruses, and other foreign substances. These proteins are specifically designed to recognize and bind to antigens, which are molecules that the immune system identifies as foreign or harmful. Antibodies play a crucial role in the immune response by marking pathogens for destruction by other immune cells and signaling the immune system to attack the invaders. Therefore, antibodies are primarily made up of proteins.
