C) nucleic acids
D) lipids

Question

Quizplus · Accepted Answer

Proteins are embedded in phospholipid bilayers and act as transporters for hydrophilic molecules into or out of the cell. These proteins can be either channels, which allow specific molecules to pass through, or carriers, which bind to the molecule and move it across the membrane. Carbohydrates and nucleic acids are not typically involved in membrane transport, and lipids are not specific enough to transport hydrophilic molecules.
