Question

MHC I molecules present

a) Exogenous antigens
b) Endogenous antigens
c) Haptens
d) Antibodies

Answer 1

MHC I molecules present endogenous antigens, which come from inside the cell, and are found on the surface of all nucleated cells in the body.

Step-by-step explanation:

MHC I molecules present endogenous antigens. These antigens come from inside the cell, such as viral or tumor proteins. MHC I molecules are found on the surface of all nucleated cells in the body and play a key role in presenting these antigens to the immune system. This helps the immune system identify and eliminate infected or abnormal cells.
