Question

The direction of the electrochemical gradient for Na+ is:

A. opposite to the electrical gradient for Na+
B. the same as the concentration gradient for Na+
C. the same as the electrochemical gradient for K+
D. the same as the concentration gradient for K+

Answer 1

C. the same as the electrochemical gradient for K+

Step-by-step explanation:

The direction of the electrochemical gradient for Na+ is: C. the same as the electrochemical gradient for K+

The electrochemical gradient is the sum of the electrical and chemical forces acting on an ion

• Na+ and K+ are both positive ions so will experience the same electrochemical gradient.

• A Na+ and K+ pump puts Na+ outside the membrane and K+ into it.

Answer 2

B. the same as the concentration gradient for Na+

Step-by-step explanation:

The net electrochemical gradient movement of potassium is to move into the cytoplasm of the cell, and the net electrochemical gradient of sodium is to move into the extracellular fluid. There is an overall negative net charge inside the cell than compared to the outside because of this
