Which of the following statements correctly describes the electrical gradient for K⁺? A)It favours its movement out of the cell at resting potential. B)It favours its movement into the cell at resting potential. C) It favours the concentration gradient for K⁺ at the equilibrium potential for K⁺. D) The larger the electrical gradient, the lesser is the equilibrium potential.

Question

Quizplus · Accepted Answer

The electrical gradient for K⁺ favours its movement into the cell at resting potential because the inside of the cell is negatively charged relative to the outside due to an excess of intracellular anions and extracellular cations. This means that positively charged ions, such as K⁺, are attracted to move into the cell.
