Membrane Potentials: Instructor version of student Web Tutorial 45.1 that examines how an electrochemical gradient is formed across the neuronal plasma membrane by the differential distribution of sodium, potassium, and chloride ions and negatively charged proteins. The establishment of a membrane potential is seen using a graph of a voltmeter as ions move across the membrane. An interactive exercise designed to teach the student how voltage gated channels work comes next. Finally, the action of the sodium-potassium pump is diagrammed showing the pumping of 3 sodium ions outward for every 2 potassium ions inward. Run time: 4:40 |
