Early in a primary immune response, antibodies are often
produced before extensive affinity maturation has occurred. Despite
having relatively low affinity at individual antigen-binding sites, these early
antibodies can still bind pathogens effectively and contribute to immune
protection.

Which explanation BEST accounts for the
effectiveness of IgM during this early phase?

Answer

The
pentameric structure of IgM provides high overall binding strength through
multiple binding sites

Answer

IgM
rapidly undergoes affinity maturation immediately after secretion

Answer

IgM
diffuses more efficiently into infected tissues

Answer

IgM
is preferentially selected for high-affinity antigen binding
