Question

Draw, label and annotate a graph of quantity of antibody in blood over time to compare primary and secondary immune responses. Explain differences.

Accepted Answer

Greater peak of antibody conc of secondary responseGradient of secondary response steeperTime taken for response to occur lower in secondarySecondary response lasts longerReason: memory cells already present after primary response and they are ready to release immune response quickly for that specific pathogen & no need for antigen recognition and clonal selection
