Question

Materials essential to life processes move across a cell membrane through a variety of methods. What cell membrane structure allows water-soluble materials to be passively transported to the cytoplasm?

Answer 1

Answer: carrier proteins

Explanation: Proteins in the cell membrane that assist with facilitated diffusion are known as carrier proteins, or transport proteins, since they carry materials across the cell membrane.

Carrier proteins bind to a molecule on one side of the membrane, change shapes to shield the molecule from the lipid bilayer, and then release the molecule on the other side of the membrane.

Answer 2

carrier protein in the call mambrane that assist with facilitated diffusion are known as carrier proteins since they carry material across the mambrane. Carrier proteins bind to a molecule on one side of the mambrane change shape to shield the molecule from the lipid bilayer, and then release the molecule on the other side of the membrane.
