Answer #1

The concentration in the cytosol is 30 times greater than the ECF therefore the concentration gradient tends to drive the potassium ions out of the cell.

So it's true statement

Concentration in the ECF is 15 times greater than the cytosol so the chemical gradient tend to drive the Na+ ions into the cell.

Hence second statement is false.

The membrane is equally permeable to all ions

Because ions can not simply cross the membrane at which there are different concentrations inside and outside of the cell.

Hence it's true statement.

The standard free energy that is required for the sodium-potassium ATPase to pump two K+ ions into the cell and three Na+ ions out is +43.8 kJ/mol but the standard free energy change of hydrolysis of ATP is only -32 kJ/mol. This apparent imbalance of free energy can be accounted for because: A) the movement of Na+ ions is down the concentration gradient . B) the movement of K+ ions is down the concentration gradient. C) the free energy provided...

Determine whether the following statement is true or false and then explain why in one or two sentences. The membrane potential results from charges moving across the membrane that has a very small effect on the concentrations of the ions, and as a result there is only a very minor difference in the number of negative and positive ions on each side of the membrane. Determine whether the following statements are true or false and then explain why in one...
