Question 1

Immunity that involves the antibodies which are produced by the B cells.

• Production of antibodies

Answer 1

HUMORAL IMMUNITY

Question 2

Immunity that involves the T cells which are the ones recognizing the antigens.

Answer 2

CELL-MEDIATED IMMUNITY

Question 3

It trigger the production of antibodies.

• Present in microbes/microbial cell

Answer 3

ANTIGENS

Question 4

It is produced by the B cells. They are globular proteins (immunoglobulins) made in response to an antigen.

It is secreted by plasma cells in the blood. Able to cross the placenta into the fetus.

• Most abundant immunoglobulin

Answer 9

IgG

Question 10

It is the biggest antibody (macroglobulin)

• May be attached to the surface of a B cell or secreted into the blood.

Answer 10

IgM

Question 11

It is found on the surface of the B cells.

Answer 11

IgD

Question 12

A role of antibodies where the antibody will bind to the spike proteins; microbes will be inhibited from entering the host cell.

Answer 12

NEUTRALIZATION
