What is the difference between T cell receptors and MHC molecules?
Wiki User
∙ 13y ago
T cell receptors bind to MHC class 1 molecules. MHC class 1 molecules bind to peptides (self or foreign) and present it to the cell's membrane. The job of a T cell is to decide what is presented on the MHC class 1 cell whether to leave it alone or to activate to destroy it because it is non-self.

What often serve as receptors or cell recognition molecules on cell surfaces?
Glycoproteins
Neurotransmitters attach to what molecules in the cell membrane?
Neurotransmitters attach to proteins with sugars attached. The receptors then tell the molecules what to do and where to go in the cell.
The molecules that convert extracellular signals into intracellular ones are?
cell surface receptors
What are the functions of Plasma Membrane?
erves as a gateway between the fluid inside and outside the cell. Keeps the cell whole and intact. It also prevents larger molecules or particles from entering it. Receptors (bind molecules and trigger responses within the cell) Enzymes (catalyze certain reactions)
What transmits information into a cell by binding to signal molecules?
One of the most common molecules of the cell that transmit information from outside to inside are transmembrane receptors. Typically, a ligand will bind to to exterior portion and trigger receptor activation, leading to downstream signaling within the cell.
What do IgE antibodies T cell receptors and MHC molecules have in common?
They are all players of your adaptive immunity.
What molecule binds to the receptor to start the reaction inside the cell?
Cells have proteins called receptors that bind to signaling molecules and initiate a response.Different receptors are specific for different molecules. That means that they will respond only to that signal. Your eyes respond to light but your ears do not.There are hundreds of receptor types found in cells, and varying cell types have different populations of receptors.
When large molecules bind to receptors on the plasma membrane and are then engulfed by cell the process is called what?
Receptor-mediated endocytosis :)
A specific protein that recognizes certain molecules?
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
Glucose and no other sugar is transported into cells by protein carrier molecules in the cell surface membrane. How do carrier molecules specifically recognize glucose?
the receptors on the protein carrier recognise glucose allowing it to enter the cell :)
What is the difference between protein hormones and steroid hormones and how they communicate with their target cells?
Steroid hormones arelipid-soluble and can dissolve easily into the cell membrane of the target cell to connect with receptors. Protein hormones are water-soluble and connect with receptors at the membrane because it can't diffuse through the membrane.
What is the Cell that receives and transmit information?
nerve cell or receptors nerve cell or receptors nerve cell or receptors
