Question

In order to be detected by a T cell, the class I major histocompatibility (MHC) molecule of infected cells must go through the process of ________.

A) perforin incorporation
B) antibody binding
C) phagocytosis
D) antigen presentation
E) complement activation

Answer 1

The class I major histocompatibility (MHC) molecule of infected cells must undergo the process of antigen presentation to be detected by a T cell, involving presenting pathogen's antigens along with an MHC molecule on the surface of antigen-presenting cells.

Step-by-step explanation:

In order to be detected by a T cell, the class I major histocompatibility (MHC) molecule of infected cells must go through the process of antigen presentation. This complex immunological process involves antigen processing and presentation by professional antigen-presenting cells, such as dendritic cells, macrophages, and B cells. After internalizing and processing the pathogen, these cells present the pathogen's antigens in conjunction with the MHC molecule on their surface. T cells can then recognize and respond to these antigen-MHC complexes. The correct answer to the student's question is D) antigen presentation.
