Which of the following best describes antibodies?
1.made by phagocytes and specific to one antigen
2.made by lymphocytes and specific to one antigen
3.made by leucocytes and non-specific
4.made by phagocytes and non-specific
Answers:
2 * B lymphocytes respond to the presence of an antigen by differentiating into plasma cells and manufacturing antibodies that react near the antigen that activated them.
Lymphocytes are the white blood cells important within the immune system, and they work in concert with phagocytic cells to combat infections. However, the role lymphocytes play surrounded by fighting infections is very different than that played by phagocytes. Lymphocytes, with the facilitate of antigen-presenting cells, are part of what is called the adaptive immune system. This system have three important features that all depend on lymphocytes.
1. Specificity. B cells/antibodies or T cells act in response specifically with the antigen that activated them and they generally do not take action with any differently structured antigens. These reactions are as specific as the binding of substrate to the active site of an enzyme; within fact, antigen-antibody reactions share many features next to enzyme-substrate binding.
Whereas phagocytes are...
White blood cells that can engulf (by phagocytosis ) and destroy microorganisms including virus. Source(s): http://www.microbiologytext.com/index.ph…
