What Is The Difference Between Membrane Potential And Resting Potential? The difference between the membrane potential and the equilibrium potential (-142 mV) represents the net electrochemical force driving Na+ into the cell at resting membrane potential. At rest, however, the permeability of the membrane to Na+ is very low so that only a small amount
What Is The Role Of A Phospholipid Bilayer? The phospholipid bilayer is critical in maintaining the integrity of the cardiomyocyte, as it forms a permeability barrier that provides a physical interface between the inside and the outside of the myocyte. It also contains key enzymes and ion channels that regulate ionic gradients across the cell
What Happens To The Membrane Potential If You Increase Sodium Permeability? If you experimentally increase the permeability of an axonal membrane to sodium ions, the equilibrium potential for sodium in the cell will a. increase, because the influx of sodium depolarizes the neuron. What happens when Na+ permeability increases? The key point is that the
What Factors Affect Simple Diffusion? What factors affect simple diffusion? Factor Reason The concentration gradient The greater the difference in concentration, the quicker the rate of diffusion. The temperature The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. What are the 5 factors that
What Factors Increase Rate Of Diffusion? What factors increase rate of diffusion? The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
