Quizplus · Accepted Answer

A protein's surface is in contact with the outside environment, so it needs to be able to interact with other molecules. Both polar and non-polar amino acids can be found on the surface of a protein, with polar amino acids being more common. This allows for a variety of interactions with both polar and non-polar molecules.
