What is the Difference between membrane potential and equilibrium potential?

∙ 11y ago
Equilibrium potential is referring to the equilibrium (or balance) established between the forces of diffusion and electrical forces specific to each ion. For example, the equilibrium potential for Potassium, K+, in a cell with a semi permeable membrane is -80mV or Ek+=80mV. The membrane potential, on the other hand, refers to the voltage across the membrane at anytime and takes into account a range of equilibrium potentials such as Potassium, Sodium etc.

What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
The electrical charge resulting from the difference between the positive and negative ions outside and?
The resting membrane potential
What influences the movement of ions and molecules across cell membranes?
A membrane potential is basically the difference between the inside and outside of the cell. Ions are charged, and so will change the membrane potential (the difference between charges on the inside and outside) when they move. Please see the related link below which includes a diagram of how ions affect membrane potential.
What is difference between physical and chemical balance?
The difference is that chemical equilibrium is the equilibrium of products and reactants in a reaction while physical equilibrium is the equilibrium of the physical states of the same substance.
What is the difference between an isotonic solution and equilibrium?
equilibrium is reaching that state of equal concentration. isotonic is how you describe the cell that has equal concentration.
Electrical charge resulting from the difference between positive and negative ions outside and inside the brain cell membrane is called?
Membrane potential

It is the membrane potential of a neuron at rest?
Yes,the membrane potential of a neuron is at rest because it is the difference in electrical charge between inside and outside a resting neuron.
What is the difference between diffusion potential and nernst potential?
The Diffusion Potential is the potential difference across the boundary b/w two electrolytic solutions of different compositions The Nernst Potential is the diffusion potential across a membrane that exactly opposes the net diffusion of a particular ion through the membrane
What is resting potential?
A rest potential is the potential difference between two sides of the membrane of nerve cells when the cell is not conducting an impulse. =)
The electrical charge resulting from the difference between the positive and negative ions outside and?
The resting membrane potential

Which is a major difference between the cell membrane and the cell wall?
Which is a major difference between the cell membrane and the cell wall
How much potential difference is there between two identical charges?
There is no potential difference between identical charges
What is the difference between q and K in determining an equilibrium constant?
K is the equilibrium constant, Q is a concentration.
What is the difference between electrical potential and electromotive force?
electric potential is potential difference between two points in closed circuit. but electromotive force is potential difference in any open circuit.
What is the relationship between speciation and the theory of punctuated equilibrium?
No difference.
