Cell Biology: Passive Transport Mechanisms

To synthesize proteins for cellular functions

To modify the structure of molecules

To actively pump molecules against their gradients

To provide corridors for specific molecules or ions to cross membranes (correct)

They facilitate the movement of proteins

They assist in the facilitated diffusion of water (correct)

They transport large molecules via active transport

They facilitate the movement of ions only

They are always open regardless of a stimulus

They only transport larger molecules

They open or close in response to specific stimuli (correct)

They function by converting energy into movement
