Make sure you include all structures involved in the creation and maintenance of the resting membrane potential. Explanation addressing the question above Membrane potential is the difference in electric potential between the interior and the exterior of a biological cell. With respect to the exterior of the cell, typical values of membrane potential range from -40 mV to -80 mV. The membrane potential has two basic functions as a battery and transmitting signals between different parts of a cell. In non-excitable cells, the membrane potential is held at a relatively stable value, called the resting potential. The resting membrane potential of a neuron is about -70 mV. At rest, there are relatively more sodium ions outside the neuron and more potassium ions inside that neuron. It is determined by concentration gradients of ions across the membrane and by membrane permeability to each type of ion. Structure and…arrow_forward

- a)The distribution of sodium ions across the cell membrane of a neuron is 20 mmol/L inside the cell and 200 mmol/L outside the cell. When the system reaches equilibrium, the concentration of sodium ions will be identical on both sides of the cell membrane. What is the standard Gibbs energy difference in the system? Assume the system is at body temperature (37 °C). b)What is the Gibbs energy difference across the membrane in the initial state (prior to reaching equilibrium)?arrow_forwardSeparately, draw a table using arrows to depict the appropriate magnitude and direction of the forces and ion fluxes at different membrane potentials for a ligand-gated channel that is equally permeable to both ion X+ and ion Y+. The equilibrium potential for ion X+ is -60 mV, and the equilibrium potential for ion Y+ is -20 mV. Which item best represents the forces and fluxes for a membrane potential of -40 mV (a, b, c, or d)? Upwards arrows means outward direction and downwards arrow means inward direction. The length of the arrow determines the magnitude.arrow_forwardWhich of the following statements best describes the features of voltage-gated K+ channels? They consist of 4 subunits, are activated at the same time as voltage-gated Na+ channels, but do not inactivate. They consist of 4 subunits, are activated by depolarisation and close slowly during the refractory period. They have 24 membrane spanning alpha helices, 4 of which have positively charged amino acids which promote a conformational change in the channel following depolarisation. They consist of 4 subunits and are open at rest which causes the resting membrane potential to be close to the K+ equilibrium potential.arrow_forward

The equilibrium potential for ion X+ is -60 mV, and the equilibrium potential for ion Y+ is -20 mV. Which item (a, b, c, or d) best represents the forces and fluxes for a membrane potential of +20 mV? Upwards arrows means outward direction and downwards arrow means inward direction. The length of the arrow determines the magnitude.arrow_forwardIon channels, such as the K+ channel, can have open and closed forms that respond to membrane potential. In addition, an amino-terminal domain, called the inactivation domain or inactivation gate, can block the channel. This is called the ball and chain model of channel inactivation. Identify the statements that correctly describe the ball and chain model. The inactivation gate can only inactivate a channel that has closed in response to depolarization. A shorter tether or chain peptide strand attached to the inactivation domain would increase the time required to inactivate the K+ channel. A mutation causing the loss of the inactivation gate in K+ channels could result in a membrane that undergoes repolarization more slowly. After depolarization and channel opening, the inactivation gate soon occludes the open channel.arrow_forwarddescribe what the resting membrane potential of a cell is. What is the resting membrane potential of neurons (give units)? What are the two factors that generate the resting membrane potential? Think of scenarios that change the factors that generate the resting membrane potential and how that would change the overall resting membrane potential.arrow_forward
