What is the significance of the cl- equilibrium potential in determining the resting membrane potential of a neuron?
The equilibrium potential for chloride ions (Cl-) plays a significant role in determining the resting membrane potential of a neuron. This is because the movement of chloride ions across the cell membrane can influence the overall balance of ions inside and outside the neuron, which in turn affects the resting membrane potential. If the equilibrium potential for chloride ions is altered, it can lead to changes in the resting membrane potential and impact the neuron's ability to transmit signals effectively.

What is the significance of the equilibrium potential in determining the resting membrane potential of a cell at cl equilibrium?
The equilibrium potential is important in determining the resting membrane potential of a cell because it represents the voltage at which there is no net movement of ions across the cell membrane. At this point, the concentration gradient and electrical gradient for a specific ion are balanced, resulting in a stable resting membrane potential.

What are the forces at equilibrium potential?
At equilibrium potential, the forces on an ion are balanced, meaning there is no net movement of ions across the membrane. The electrical force due to the membrane potential balances the chemical force due to the concentration gradient, resulting in equilibrium. This can be seen in action for ions like potassium (K+) at its equilibrium potential in a resting neuron.

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.
What is equilibrium potential for sodium?
The equilibrium potential for sodium (ENa) is around +60 mV. This is the membrane potential at which there is no net movement of sodium ions across the membrane, as the concentration gradient is balanced by the electrical gradient.
Through the membrane of a resting neuron highly permeable to potassium ions its membrane potential does not exactly match the equilibrium potential for potassium because the neuronal membrane is?
The neuronal membrane also has ion channels for other ions besides potassium, such as sodium or chloride, that can influence the resting membrane potential. These other ions contribute to the overall equilibrium potential of the neuron, which affects its resting membrane potential. Additionally, the activity of Na+/K+ pumps helps establish and maintain the resting membrane potential, contributing to the slight difference from the potassium equilibrium potential.
What are the forces at equilibrium potential?
At equilibrium potential, the forces on an ion are balanced, meaning there is no net movement of ions across the membrane. The electrical force due to the membrane potential balances the chemical force due to the concentration gradient, resulting in equilibrium.

Is equilibrium potential the same as resting potential?
The equilibrium potential refers to the electrochemical potential at equilibrium of a particular ion, as calculated by the Nernst equation. The resting potential refers to the weighted average based upon membrane permeabilities of all the equilibrium potentials of the various ions in a given cell, as calculated by the Goldman equation.
Why resting membrane potential value sodium is closer to equilibrium of potassium?
The resting membrane potential value for sodium is closer to the equilibrium of potassium because the sodium-potassium pump actively maintains a higher concentration of potassium inside the cell and a higher concentration of sodium outside the cell. This leads to a higher permeability of potassium ions at rest, resulting in the resting membrane potential being closer to the equilibrium potential of potassium.
Who is equation is used to calculate equilibrium potential for a particular ion?
The Nernst equation is used to calculate the equilibrium potential for a particular ion. It takes into account the ion concentrations inside and outside the cell, as well as the charge of the ion, to determine the membrane potential at which there is no net movement of that particular ion across the membrane.
What will be the solute potential and pressure potential of the cell at equillibrium?
At equilibrium, the solute potential of the cell will be equal to the solute potential of the surrounding solution, as there will be no net movement of water molecules. The pressure potential will also be equal to zero, as there will be no additional pressure exerted on the cell membrane. This balance of solute and pressure potentials at equilibrium ensures that there is no net movement of water into or out of the cell.
