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.
Which is the correct term for the movement of an electrical charge across a membrane?
Potential difference.
Why is there a resting membrane potential across the cell membrane?
sodium/potassium pump
What substances plays a mojor role in generating the membrane potential of a neuron?
Well, for starters, membrane potential is a separation of charges across the membrane. So i think what you mean is "generating the action potential in a neuron". So in that case The substance that plays a major role in generating an action potential is Sodium (Na+). However, if you really mean membrane potential, there is only two substances associated with that and those are sodium (Na+) and potassium (K+).However, in truth, the generation of an action potential depends on the ligand and its receptor.
What is the Difference between membrane potential and equilibrium potential?
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.

The difference in the concentrations of a substance across a cells membrane?
action potential
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
