Describe an Action Potential Using Sodium Potassium and Membrane
Useful information about the selectivity of membrane action can be obtained by studying the effects of biocides on protoplasts and spheroplasts suspended in various solutes. A refractory period follows an action potential corresponding to the period when the voltage-gated sodium channels are inactivated. Resting Membrane Potential Of Nerves The Hodgkin-Huxley Model for the Generation of Action Potentials. . Mitters with muscle membrane receptors causes the membrane to become permeable to sodium resulting in the influx of sodium ions and 6 of the membrane. Once the cell reaches threshold voltage-gated sodium channels open and being the predictable membrane potential changes describe above as an action potential. 7 During phase 2 potassium efflux and calcium in-flux offset one another so that the electrical charge across the cell membrane remains the same and the so-called plateau phase of the action potential is created Fig. ...
