Question

The plasma membrane is composed of a phospholipid bilayer with embedded proteins. What is one of the functions of the embedded proteins?

Answer 1

Diffusion/passive transport. Requires protein channels to allow passage through the membrane

Answer 2

Embedded proteins act as signalling molecules and as transport proteins.

Step-by-step explanation:

Integral and transmembrane proteins are embedded proteins acting to transmit signals from outside the cell to the inside.

Others act as transport proteins that form channels that allow movement of molecules between the inside and outside the cell.
