masalah 1

pilihan

What is the primary function of the acquired immune response?

  • To produce antibodies
  • To provide immediate defense against infections
  • To remember pathogens for faster response upon re-exposure
  • To create physical barriers against pathogens

masalah 2

pilihan

Which of the following cells is primarily involved in the acquired immune response?

  • Red blood cells
  • B lymphocytes
  • Platelets
  • Macrophages

masalah 3

pilihan

What are antibodies?

  • Cells that engulf pathogens
  • Proteins that neutralize antigens
  • Lipids that store energy
  • Nucleic acids that store genetic information

masalah 4

pilihan

Which part of the immune system is responsible for the memory aspect of acquired immunity?

  • Memory B cells
  • Cytotoxic T cells
  • Helper T cells
  • Natural killer cells

masalah 5

pilihan

What role do T cells play in the acquired immune response?

  • They produce antibodies
  • They assist B cells and directly kill infected cells
  • They form physical barriers
  • They produce red blood cells

masalah 6

pilihan

Which molecule is primarily responsible for antigen recognition by B cells?

  • Antigens
  • MHC molecules
  • Antibodies
  • Cytokines

masalah 7

pilihan

Which type of T cell is primarily involved in helping B cells produce antibodies?

  • Cytotoxic T cells
  • Helper T cells
  • Regulatory T cells
  • Natural killer cells

masalah 8

pilihan

How does the acquired immune system differentiate between self and non-self?

  • Through physical barriers
  • By producing antibodies
  • Through recognition of specific antigens
  • By using MHC molecules to present antigens

masalah 9

pilihan

What is the result of a failure in the acquired immune system to distinguish self from non-self?

  • Autoimmune diseases
  • Allergies
  • Immunodeficiency
  • Cancer

masalah 10

pilihan

What is the primary function of the humoral immune response?

  • To produce antibodies against pathogens
  • To destroy infected host cells
  • To activate the complement system
  • To mediate allergic reactions

masalah 11

pilihan

Which type of lymphocyte is primarily responsible for the humoral immune response?

  • B cells
  • T cells
  • Natural killer cells
  • Macrophages

masalah 12

pilihan

What role do antibodies play in the humoral immune response?

  • They directly kill pathogens
  • They neutralize and mark pathogens for destruction
  • They activate T cells
  • They produce cytokines

masalah 13

pilihan

Which antibody is the most abundant in the bloodstream during a primary immune response?

  • IgA
  • IgG
  • IgM
  • IgE

masalah 14

pilihan

What is the role of memory B cells in the humoral immune response?

  • To immediately fight off infections
  • To remember past infections and respond faster upon re-exposure

masalah 15

pilihan

Which component of the immune system helps antibodies by forming a membrane attack complex?
