Hey, everyone. Let's take a look at this question together. What is the main function of class two Mh C molecules? Is it answer choice. A presenting exogenous antigens. Answer Choice B interacting with cytotoxic T cells. Answer choice C displaying endogenous antigens or answer choice D facilitating phagocytosis. Let's work this problem out together to try to figure out which of the following answer choices is the main function of class two Mh C molecules. So in order to solve this question, we have to recall what we have learned about the class two MH C molecules and what their main function is to determine which of the following answer choices is the correct answer. And we can recall that the class two Mh C molecules function to present exogenous antigens, which those exogenous antigens are derived from extracellular sources and are taken up by antigen presenting cells digested and then displayed on the cell surface using those class two MH C molecules. And looking at our answer choices, we can identify answer choice A as the correct answer since it says, presenting exogenous antigens, which is the main function of those class two MH C molecules and all other answer choices are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
