Question

a gated channel protein is always open to allow molecules to pass through as part of the process of facilitated diffusion. true or false

Explanation:

Gated channel proteins in facilitated diffusion are not always open. They open and close in response to specific signals (like voltage changes, ligand binding), unlike non - gated (e.g., aquaporins in some cases) or always - open channels. So the statement is false.

Answer:

False
