Which of the following best describes antibodies?
A
are lipids that destroy pathogens by disrupting their membranes
B
are nucleic acids that encode immune system receptors
C
are proteins produced by B cells that specifically bind to antigens
D
are carbohydrates that serve as energy sources for immune cells
Verified step by step guidance1
Understand the role of antibodies in the immune system: Antibodies are molecules that help the body identify and neutralize foreign substances called antigens.
Recall the biochemical nature of antibodies: Antibodies are made up of amino acids, which classifies them as proteins.
Identify the cell type responsible for producing antibodies: B cells, a type of white blood cell, produce antibodies in response to the presence of antigens.
Recognize the specificity of antibodies: Each antibody binds specifically to a particular antigen, allowing targeted immune responses.
Eliminate incorrect options by matching their descriptions to known biological molecules: lipids disrupt membranes, nucleic acids encode genetic information, and carbohydrates serve as energy sources, none of which describe antibodies.
