Questions & Step-by-Step Solutions
What is the function of the Fc region of an antibody?
Step 1: Understand that antibodies are proteins made by the immune system to help fight infections.
Step 2: Know that antibodies have two main parts: the Fab region (which binds to the target) and the Fc region (which interacts with other parts of the immune system).
Step 3: The Fc region is the tail part of the antibody that does not bind to the target directly.
Step 4: The Fc region can bind to specific receptors on immune cells, like macrophages and natural killer cells, helping them recognize and destroy pathogens.
Step 5: The Fc region also activates the complement system, which is a group of proteins that helps to kill bacteria and clear away dead cells.
