The sum of the electrical and chemical forces acting on an ion is known as its ____
|
|
permeability gradient
|
|
|
therndoynamic difference
|
|
|
electrochemical gradient
|
|

Explanation:
Detailed explanation-1: -Concentration gradient is the change in concentration of a substance over a given distance. An electrical gradient is a change in electric potential over a given distance. An electrochemical gradient is a change in the concentration of ions across a membrane or membrane potential.
Detailed explanation-2: -The concentration gradient of a particular ion is the difference of concentration of this ion between the two sides of the plasma membrane. Ions passively move through open channels from the medium where their concentration is high to the medium where their concen-tration is lower.
