What regulates the rate of facilitated diffusion?

Question

Quizplus · Accepted Answer

The rate of facilitated diffusion is regulated by the membrane-bound transport protein, which facilitates the movement of specific molecules across the cell membrane. The level of energy available to support the transport is not directly involved in facilitated diffusion, as it does not require energy input. The permeability of the cell membrane is a factor that influences the overall movement of molecules across the membrane, but it is not specific to facilitated diffusion alone. Net movement of water across the cell membrane is not directly related to facilitated diffusion, as it pertains to the movement of water molecules rather than other solutes.
