Why the rate of diffusion of a substance along the concentration gradient does not increase continuously, while the concentration difference of the molecules across the membrane increases? |
|
|
a) |
Process of facilitated diffusion need ATP |
|
b) |
As concentration difference increases, molecule interfere with one another |
|
c) |
100% saturation of carrier protein after some time |
|
d) |
Transport proteins must be of channel protein type |

(c) The rate of diffusion of a substance along the concentration gradient does not increase continuously. While the concentration difference of the molecules across the membrane increases when the process is of carrier type. This happens because after a certain level, the carrier protein gets saturated |
