Question

Organ donation saves many lives each year. Even though some transplanted organs are derived from living donors, the majority come from patients who die but still have healthy organs that can be of value to a transplant recipient. Potential organ donors can fill out an organ donation card to specify their wishes. If the donor is in critical condition and dying, the donor's family is usually consulted to discuss the donation process. Generally, the next of kin must approve before donation can occur, regardless of whether the patient has completed an organ donation card. In some cases, a family member overrides the donor's wishes. Do you think that family members should be able to overrule the stated intentions of the potential donor? Why or why not? Have you signed up to be an organ donor? Why or why not?

Accepted Answer

Hey everyone. Let's take a look at this question together. Which of the following molecules is responsible for the rejection of organ transplants. Let's recall what we know about the process of organ transplants. To try to figure out which of the following molecules is responsible for the rejection of an organ transplant. We know that when we're talking about organ transplants, what is responsible for the organ transplant is the immune system. Now in the immune system. It's basically looking at that organ that's being transplanted to look for specific M. H. C one proteins. And so in these proteins are basically receptors that let that immune system know whether or not it can accept or reject the organ for a transplant. And so these MHC one proteins are those molecules that are responsible for the detection of that organ that is being transplanted, whether or not it can be accepted or rejected. And so the MHC MHC one protein stands for major historic compatibility complex or answer choice A because the major histone compatible complex encompasses the MHC one proteins as well as those MHC two and three proteins with the MHC one proteins being those responsible for rejection of organ transplants. Making a the correct answer. And we can also eliminate answer choice B, C and D. Because cytokines control growth interference are another type of cytokines. And then complement proteins are proteins that are found in blood and so answer choice A is the only one here that is a molecule that is responsible for the rejection of organ transplants.
