A vаriety оf аntibоdies, оn the order of one hundred million different types, circulаte in the bloodstream, searching for foreign invaders to attack. Once discovered, the antibody binds the invader with its flexible arms containing the Fab region. Thin flexible chains connect these flexible arms to the antibody base, called the Fc region. This base determines which class the antibody belongs to, as some antibodies have four or ten binding sites due to their structural formation. The following figure shows an immunoglobulin image: a. Label the light and heavy chains on the structure. Light Chains [Option1] Heavy Chains [Option2] b. How many specific antigen-binding sites are there on the immunoglobulin molecule depicted? [Option3]
