ACTIONS OF ANTIBODIES

Which is the mechanisms of antibodies except Agglutination?

• Opsonisation

• Neutralisation

• Precipitation

• Inflammation

• Lysis

What is the name of mechanisms shown above?

(a)  

What is the name of structure label y?

• Antigen

• Toxin

• Antibody

• Bacterium

What is the function of label z?

• Bind with toxins produced by bacteria and neutralise the toxin.

• React with dissolved antigns to form an insoluble complex that is easily destroyed by phagocytes.

• Combine with antigens and act as a marker for phagocytes to recognise the antigens and destroy them.

Neutralisation of antibody also known as ............

• Sterilizing antibody

• Sterilizing immunity

• Neutralizing immunity

• Sterilizing toxin

What is x?

• Antibody

• Bacterium

• Antigen

• Precipitation of antigen molecules

Which of these actions of antibody is Neuralisation?

• 
• 
• 
• 
• 

What will happen if theres no opsonisation process?

• The recognition and destruction of invading agents such as bacteria would be inefficient.

• The recognition of invading agents such as bacteria would be inefficient.

• The destruction of invading agents such as bacteria would be inefficient.

What is similarity between precipitation and agglutination?

• The antigen involved,comparatively smaller.

• React with solube substances.Example, proteins.

• Antibody crosslink antigen and form precipitation.

State one category of agglutination process.
