Proteins that extend all the way across the membrane are called transmembrane proteins. The portions of an integral membrane protein found inside the membrane are hydrophobic, while those that are exposed to the cytoplasm or extracellular fluid tend to be hydrophilic.The hydrophilic, or “water-loving,” portion of a phospholipid is its head, which contains a negatively charged phosphate group as well as an additional small group (of varying identity, “R” in the diagram at left), which may also or be charged or polar...So the correct ans is A ....Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane. They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions.

For the tertiary structure of proteins in an aqueous/polar environment, hydrophobic amino acids are located on the surface of the protein whereas non-polar amino acids are located in the interior. Let’s assume that the protein was normally in an environment with just the opposite composition, that is a non-polar, hydrophobic environment (for example liquid methane). What would the orientation of the polar and non-polar amino acids be? Explain.
