Which of these is not a function of some membrane proteins?

A. Keeping the cell from dissolving

B. Transmitting messages to cell organelles

C. Catalyzing chemical reactions in the cell

D. Allowing ions to enter the cell

A

Explanation:

D) Examples of membrane proteins include ion channels, receptor proteins, and proteins that allow cells to connect to each other.

C) Almost every chemical reaction in a cell is catalyzed by a class of proteins called enzymes

B) Membrane proteins are the nanomachines that enable membranes to send and receive messages and to transport molecules into and out of cells and compartments.

A) Proteins that are anchored by dissolving in the bilayer core are said to be integral to the membrane. Lipids: Lipid-soluble substances (e. g. alcohol, chloroform) can dissolve into the bilayer and thus cross the membrane.
