Answer: Option C is correct.
Explanation:
Membrane proteins are of two types.
i. Integral proteins (Intrinsic proteins) contain hydrophobic membrane spanning regions. they can serve as membrane receptor as they contain a cytoplasmic domain to transmit the signal.
ii. Peripheral proteins (Extrinsic proteins) float on the lipid bilayer. They can not serve as membrane receptors on their own as they lack a cytoplasmic domain to transmit the signal. However, a peripheral protein can serve as a co-receptor by associating with another intrinsic protein.

Which of the following statements correctly matches a membrane
protein with its function.
-Structural proteins bind to molecules to facilitate entry to
or exit from the cell.
-Carrier proteins form water-filled channels that allow
molecules to pass through.
-Channel proteins are classified as uniport, symport, or
antiport carriers.
-Receptors transmit signals from the extracellular environment
to the cytoplasm of the cell.
During the cephalic phase of gastric secretion,
-there is an increased flow of action potentials along the
vagus nerve...

SDS-PAGE is often used to determine the location and orientation of membrane associated proteins. Commonly, experimental preparations of membranes are treated in a variety of ways in order to extract the proteins, which are then subjected to SDS-PAGE. These treatments will affect membrane proteins in different ways, based on how they are arranged in the membrane. One of the most common pre-treatments is by the digestive enzyme trypsin, which degrades polypeptide chains. Trypsin is too large to cross a membrane,...
