Answer:
B. the same as the concentration gradient for Na+
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
Sodium represents by the (Na).
Melting, due to the strong forces provided by lattice energy framework, would require more energy
