In an experiment, a scientist separates two bodies of water with a thin phospholipid membrane, such as that found in a cell. He pours salt in one of the bodies of water. The membrane has channel proteins embedded. His control experiment is two bodies of water separated by the same membrane, but without the channel proteins.
WebThere are two important parts of a phospholipid: the head and the two tails. The head is a phosphate molecule that is attracted to water (hydrophilic).The two tails are made up of fatty acids (chains of carbon atoms) that aren’t compatible with, or repel, water (hydrophobic).The cell membrane is exposed to water mixed with electrolytes and other materials on the … WebNational Center for Biotechnology Information
