Questions & Step-by-Step Solutions
What is the role of antibodies in the immune response?
Correct Answer: Antibodies help in fighting infections by neutralizing toxins and marking pathogens for destruction.
Step 1: Understand that antibodies are special proteins made by the immune system.
Step 2: Know that antibodies help protect the body from harmful things like germs and toxins.
Step 3: Learn that antibodies can neutralize (block) toxins and pathogens (germs) so they can't harm the body.
Step 4: Realize that antibodies can mark pathogens for destruction, making it easier for immune cells to find and eat them (this is called opsonization).
Step 5: Understand that antibodies can also activate a group of proteins in the blood called the complement system, which helps destroy pathogens.
