Question

32. Which term best describes a feature of an antigen that makes for good interaction with an antibody?

1. Antitope
2. Carboxy terminus
3. Dalton
4. Epitope
5. Immunotope

33. Which of the following is not one of the possible functions of antibodies?

1. Acceleration of bacteria-produced toxin binding to human cells
2. Agglutination of bacterial cells
3. Coating of bacterial cells to disrupt normal pathogen function, such as use of flagella
4. Initiation of complement protein binding
5. Neutralization of virus attachment

34. Which of the following stimulate B cells to produce large amounts of antibody?

1. Cytotoxic T cells (T_C)
2. Natural killer cells (NK)
3. T helper 1 cells (T_H1)
4. T helper 2 cells (T_H2)
5. None of the above

35. Which class of major histocompatibility complex (MHC) proteins is specifically found on the surface of B cells, macrophages, and other antigen-presenting cells?

1. Class I
2. Class II
3. Class III
4. Class A
5. Class C

Answer 1

32. the right answer is " Ecapitope"

epitope is a very important part of antigen where anitbody can bind. epitope is very specific region of antigen

33. the right answer is option A or "Acceleration of bacteria-produced toxin binding to human cells"

antibodies have a main role to prevent antigen function. they can not accelarate bacteria to produce toxin bindig to human cell

34. the right answer is option A or " T helper 1 cells (T_H1)"

helper T LYMPHOCYTE does not kill infected cells directly . they stimulate B cell to produce antibodies.  T helper 1 cells (T_H1) help to stimulate B cells.

35. . the right answer is option B or "Class II"

MHC class II found on thesurface of B cells, macrophages, and other antigen-presenting cells
