Q

Why does the concentration gradient across the exchange surface

A

The greater the difference in concentration on either side of the exchange surface. The higher the rate of facilitated diffusion up to a point depending on number of channel and carrier protein available

Q

How does the number of channel or carrier proteins available in carrier proteins affect facilitated diffusion

A

Facilitated diffusion depends on using channel and carrier proteins. Once all channel proteins are used the rate of facilitated diffusion of a particular molecule cant increase.

This means the number of carrier or channel proteins available in a exchange surface, the higher the rate of facilitated diffusion
