Which of the following statements correctly describe(s) the driving forces for diffusion of na+ and k+ ions through their respective channels?

Question:

Which of the following statements correctly describe(s) the driving forces for diffusion of Na+ and K+ ions through their respective channels? Select all that apply.

A)The diffusion of Na+ ions into the cell is facilitated by the Na+ concentration gradient across the plasma membrane.

B)The diffusion of Na+ ions into the cell is impeded by the electrical gradient across the plasma membrane.

C)The diffusion of K+ ions out of the cell is impeded by the K+ concentration gradient across the plasma membrane.

D)The diffusion of K+ ions out of the cell is impeded by the electrical gradient across the plasma membrane. The electrochemical gradient is larger for Na+ than for K+.

"The concentration gradient and the electro-chemical gradient" describes  the driving forces for diffusion of Na+ and K+ ions through their respective channels

Explanation:

The Na ions diffusion inside the cell is facilitated by the concentration gradient of the Na ions which is present across the plasma membrane. Hence, the diffusion of the K ions which is present outside the cell and will be impeded due to the electrical gradient which is present near the plasma membrane. Thus, the electro-chemical gradient is greater as compared to the Na ion than that of the K ion.

the correct answer would be d. hope this !
