antibodies

Question 1

define antibodies

Answer 1

protiens with specific binding sites

Question 2

what are thee antibodies synthesised by

Answer 2

b-cells

Question 3

what do antibodys lead to

Answer 3

prepare the antigen for destruction

Question 4

how does the antibodie prepare the antigen for destruction

Answer 4

cause agglutination of bacterial cells

Question 5

what is agglutination

Answer 5

clumps of bacterial cells are formed, making it easier for phagocytes to locate them as they are less spread out around the body

Question 6

what else do antibodies do to prepare antigen for destruction

Answer 6

they serve as markers that stimulate to engulf the bacterial cells wich are attached

Question 7

what are at the two ends of the antibodie

Answer 7

antigen binding sites

Question 8

what is at the single bottom end of the antibodie

Answer 8

receptor binding site

Question 9

what is the role of a disulphide bridge in forming the quaternary structure of an antibody

Answer 9

joins two diferent polypeptides together

Question 10

what is a monoclonal antibodie

Answer 10

antibodies with the same tertiary structure or antibodies cloned from b-cells

Question 11

give one example of using monoclonal antibodies in a medical treatment

Answer 11

carriers drug to specific cells

Question 12

what can monoclonal antibodies treat

Answer 12

cancer

Question 13

whatis the process of using monoclonal antibodies to treat cancer

Answer 13

monoclonal antibodies are produced that are specific to the antigens on cancer cells.
these antibodies are then given to cancer paient and attach themselves to receptors on cancer cells.
attach to surface on cancer cells and block chemical signals that stimulate rapid growth
