Humoral response
What are antigens and where are they found?
They are proteins found in the nucleus of cells
They are proteins / glycoproteins found on the surface of cells
They are DNA fragments present in non-self organisms
They are glycoproteins which are found in the immune system

What is the main function of B lymphocytes in the immune system?
To produce antibodies
To carry out phagocytosis
To release inflammatory mediators
To activate T lymphocytes
Which statement is true about the specific immune response?
It responds rapidly because it distinguishes between different pathogens
It distinguishes between different pathogens but responds more slowly
It does not distinguish between different pathogens but responds more slowly
It responds slowly because it only involves phagocytes
Which cells in the immune system are involved in the non-specific immune response?
All white blood cells
B cells
T cells
Phagocytes
During phagocytosis the pathogen is taken in by the phagocyte, what do we call this process?
Engulfed / Exocytosis
Engulfed / Endocytosis
Exocytosis
Exocytosis / phagositised
During phagocytosis, what destroys the pathogen?
Enzymes called pathogenase
Digestive enzymes called amylase
Hydrochloric acid
Digestive enzymes called lysozymes
