If the lipid bilayer were to contain the K + channel protein, what would pass through the membrane if you added a 1 M solution of sodium chloride on the left side and a 1.5 M solution of potassium ions on the right? Assume that there is an equal amount of water on each side at the start of the experiment.

Water will move from right to left initially and after that backwards

Potassium ions through the membrane from right to left

Explanation:

Lipid bilayer is a semipermeable membrane that allows transer of only selected molecules thruogh its channel and water molecules.

In the given liplayer, K + channel is present, so only potassium ions can pass though it.

1 M solution of sodium chloride added to left

1.5 M solution of potassium chloride added to the right.

So, left side has more ions as compared to right side as 1 NaCl has two ions.

So, water will move from right to left initially, but once potassium ions will move from right to left, the water will move backwards (from left to right)
