Answer 1

1) Probiotic: Probiotics are live organisms like bacteria or yeasts that when consumed provide health benefits to the consumer. Ans: Live microorganisms that might have health benefits when consumed or applied to the body.

2) Prebiotic: Prebiotics on the other hand are molecules or substances suh as dietary fibre that enhance the growth or organisms that are already present in the body, especially the gut. Ans: Molecules in food that enhance the growth or activity of beneficial microorganisms such as bacteria or fungi in the GI tract

3) Diapedesis: Diapedesis describes the movement of cells, especially leukocytes in the body through the intact capillary. The movement is usually towards the site of tissue damage and the cells pass through the blood vessel. Ans: Movement of white blood cells through capillary wall to tissues, often accompanying inflammation.

4) Chemotaxis: Taxis means movement. Chemotaxis pertains to movement of cells or organisms in response to chemical stimuli. Ans: Movement of a motile cell up or down a concentration gradient of a particular substance.

5) Transferrin: Transferrin are molecules that are responsible for the transport of iron in the body. Ans: A molecule that binds and transport iron in blood serum

6) Siderophores: Siderophores are similar to transferrin where they bind to and transport iron. However, the molecule is present in microorganisms as opposed to human body. Ans: A molecule that strongly binds and transports iron in microorganisms.

7) Perforin: Perforin is a protein that is capable of forming pores when inserted into the target organisms. The are generally found in cytotoxic T cells and natural killer cells and act in immune response. Ans: Proteins released by killer cells to destroy targetted cells by inserting pores in the membrane.

8) Granzyme: Granzymes play a major role in the immune response as well. They are also released by natural killer cells.However, these enzymes trigger apoptosis in the target cells causing cell death. Ans: Molecules released by cytotoxic T cell and natural killer cell to induce programmed cell death (apoptosis) and so destroy target cells such as cancer cells.

9) Autograft: Auto in this case refers to self. Autograft is a type of graft where the tissue is taken from one location of the body to another location in the same body. Ans: Graft of tissue from one location to another in same individual's body.

10) Allograft: Allograft is another form of graft where the tissue is taken from one body and is grafted onto another body of the same species but not genetically identical. Ans: Graft of tissues from donor of same species to recipient but not genetically identical.

11) Epitope: Epitope is that part of the antigen that enters the body, that is recognized by the immune system. Ans: Part of antigen that an antibody recognizes and binds.

12) Antigen: Antigen is any foreign particle that enters into the body, that the body recognizes as non-self and raises antibodies against. Ans: A foreign substance or toxin that induces an immune response, especially making of antibodies.
