2. Activation of any of the Complement Cascades in response to a bacterial infection occurs rapidly because Select one: A. activation of all the pathways leads to a fast response B. bacteria are easily and quickly recognized by the initiating Complement pathway enzymes. C. the first protein in the system (Cl) is the sole protein requiring activation D. the Complement Cascade proteins are primed and ready to activate upon exposure De sequential activation of Complement enzymes expands the response at each step
1. The fact that the immune system has such great flexibility that it is able to produce such a large pool of antibody proteins in which at lease on in that pool would be able to recognize any unique antigen to which you might be exposed is because
Select one:
a. the light and heavy chain amino acid sequences vary widely within an antibody class
b. antibody proteins contain multiple antigen binding sites
c. the hyper-variable heavy chain sequence leads to wide antigen recognition
d. the amino acid sequences of the antigen binding site varies tremendously between different antibody molecules
e. an antibody protein can bind many different types of antigens Clear my choice
