Question

Write a paragraph of 3-5 sentences describing 1) whether the statement is correct or incorrect and 2) the reasoning for your answer. Your answer should demonstrate your understanding of the physiological concepts underlying the statement and be professionally written.

Assume a cell with the following properties:

[Na]out = 120 mM; [Na]in = 12 mM

[K]out = 5 mM; [K]in = 125 mM

Membrane is permeable only to Na+ and K+

If the plasma membrane of the cell becomes more permeable to Na+, both influx of Na+ into the cell and the Na+ equilibrium potential will increase.

Explanation / Answer

1.statement is incorrect

2.Because when the permeablity to sodium ions increases, the sodium ions diffuse into the cell and inside of the cell becomes more negative resulting in de polarization and the sodium equilibrium potential remains unchanged
