To study the axon of a nerve, you will reproduce the historically famous experiment of Dr Hodgkin and Dr Huxley, which was rewarded with a Nobel Prize, by setting the neuron in a test chamber to trigger action potentials with electric currents. Mass = moles molar mass In fact, you can write down an equation for the inside of the cell based on osmotic balance; you should do so. What is the role of Chloride (Cl- ions) in membrane potential? Now, what would happen if the membrane suddenly also became permeable to sodium ions? Play the Equilibrium simulation and observe the equilibrium reaction at a m. COOME For this to be true, all potentials (temperature, pressure, and chemical potential) must be the same in all of the . The flux of chloride into the cell balances the flux of chloride out of the cell, so the overall concentration will not change, even if the potential of the membrane is briefly perturbed. As long as the number of water molecules crossing from side 1 to side 2 is, on average, about the same as the number crossing from side 2 to side 1, nothing appears to change macroscopically. 23 Solution. We need constant infusions of energy to maintain a steady body temperature. Elevate your nursing program with UbiSim, a VR solution dedicated to clinical excellence.
