Question

What can we learn from the Nernst Equation (E = (2.3RT/zF)log([Io]/[Ic])?

The membrane potential generated from a charged solute distributed across a membrane

The distribution of a charged solute across a membrane

All of the above are correct

The distribution of a charged solute across a membrane resulting from a particular membrane potential

A and B only are correct

The membrane potential generated from a charged solute distributed across a membrane

The distribution of a charged solute across a membrane

All of the above are correct

The distribution of a charged solute across a membrane resulting from a particular membrane potential

A and B only are correct

Explanation / Answer

Answer : A and B only are correct

The membrane potential generated from a charged solute distributed across a membrane.

Nernst equation is used to determine the membrane potential resulted because of distribution of charged ions inside and outside of the membrane.

E - Membrane potential in mV (milli Volts)

R - Gas constant

T - Temperature in Kelvin

z - Ion charge

F - Faraday's constant

Io - External ion concentration

Ii - Internal ion concentration.
