What is on a transplanted organ that causes the transplant recipient's body to reject it?
Delvig [45]

Answer:

Major histocompatibility complex (MHC) antigens

Explanation:

The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.

A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the  transplanted organ.

Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

Why does the enzyme trypsin get deactivated when introduced in the gastric juice of the stomach?
svetoff [14.1K]
In my Biology Honors Class, they taught about gastric juice, or also known as    (p H) which is formed by stomach glands, is very acidic and can seriously mess up enzyme trypsin functions. After all, enzymes are a type of catalyst that help break down food, which means that enzymes are a sort of digestive acid as well. Hope this helps!
