QUESTION 8
The passive transport of ions across a cellular membrane is influenced by two general forces. These include 1) a chemical force, which gives
the ion a tendency to move down its own concentration gradient, and 2) the membrane potential of the cell, which indiscriminately tends to
attract positively charged ions into the cell and directs negatively charged ions to the outside. The rate with which ions move through
transport proteins will thus depend on the combined result of these two forces. Together, these two forces are known as the lon's
a concentration gradient
b. electrical charge
O electrochemical gradient
d electronegativity
