Question 4 • 2025-2026_MDCPS_2000315_Biology_1_B-CR

Which best describes the role of immunosuppressants in transplant surgeries?

Answer
A
to increase antibody production to fight off more pathogens
B
to suppress the immune system to allow pathogens to build immunity
C
to decrease antibody production to reduce the attacks on the new organ
D
to allow for recognition of antigens to determine compatibility

Explanation

After a transplant, the recipient’s immune system may recognize the new organ as foreign and attack it. Immunosuppressants lower immune activity, including antibody production, to reduce the risk of rejection. Therefore, the best choice is “to decrease antibody production to reduce the attacks on the new organ.”
