Which cells kill cancer cells and infected cells by inducing apoptosis
The blue molecule in this image is a(n) _______.
Antibody
Antigen
Pathogen
Blood cell
These cells hep to activate or program certain cells in Humoral AND Cell Mediated Response
helper T cell
mast cell
cytotoxic T cell
plasma cells
If a person has already had chicken pox, why do they generally not get sick a second time?
Memory B and T cells activate the immune system before the virus has a chance to make you sick
Natural killer cells recognize the pathogen quicker
Your 1st line of defense does a better job
Which of the following does a cytotoxic T cell have to see in order to kill an infected cell?
Antigen on MHC1
Nothing
Antigen on the body cell's MHC2
Antigen on the cell's surface
How do naive B cells become clonally selected?
They see antigen presented on an APC
They see free antigen specific to their receptor
They receive interleukins from an active Helper T cell
They see specific antigen complementary to their receptor on an APC
What happens after a clonally selected B or T cell is stimulated by interleukin from a Th cell?
It proliferates into memory cells
It clonally expands and differentiates
It becomes a T helper cell
It is able to start producing antibodies
Which is the best definition of agglutination?
Binding to the membrane of pathogens to initiate the membrane attack complex
Preventing a pathogen's cell-binding ability
Binding to toxins to prevent their harmful action
Clumping together pathogens to immobilise them + facilitate phagocytosis
Which of the following molecules do Cytotoxic T cells secrete?
Histamine
Interleukins
Granzymes + perforin
Insulin
antigen presenting cells (a) and enzymatically digest pathogens before placing antigen on their surface MHC2
Which adaptive immune response is best suited to intracellular pathogens?
Humoral
Cell-mediated
Innate
Naive T cells become clonally selected after being presented antigen on an APC's (a) molecule. This antigen must be complementary to their T cell receptor
Without these cells neither the humoral nor cell-mediated immune responses would become activated
plasma cells
neutrophils
mast cells
T helper cells
The inner chain of an antibody is known as the
heavy chain
light chain
alpha chain
beta chain
What is the name given to the bond that holds the heavy and light chain together (at two sites)
hydrogen bond
covalent bond
peptide bond
disulphide bridge
What is apoptosis?
Unexpected cell death
Cell death caused by infection
Controlled cell death
Death caused by phagocytosis
