Question 1
The more than 20 cellular proteins that function through a cascade of proteolytic actions to destroy a pathogen are known as:
◦ T-cell receptors.
◦ Immunoglobulins.
◦ Haptens.
◦ The major histocompatibility complex.
◦ Complement.
Question 2
The primary immune response involves:
◦ initial expansion of a specific B cell population upon first exposure to an antigen.
◦ initial expansion of a specific T cell population upon first exposure to an antigen.
◦ initial expansion of specific B and T cell populations upon first exposure to an antigen.
◦ initial expansion of specific B and memory cell populations upon exposure to an antigen.
◦ initial expansion of specific B, T, and memory cell populations upon exposure to an antigen.
