Membrane Potential

Question 1

*termed as voltage, electrical potential energy resulting from
the separation of oppositely charged particles
*In cells, charged particles are ions and the barrier is the plasma
membrane

Answer 1

Membrane Potential

Question 2

ranging from (-)50 – (-)90 mV.
*All cells are electrically polarized at the membrane
*The cell interior remains electrically neutral

Answer 2

RESTING MEMBRANE POTENTIAL

Question 3

*The resting membrane potential is determined mainly by the concentration gradient of K+
*Sodium drives the extracellular concentration

Answer 3

PISO, POTASSIUM
AND SODIUM
