Anybody do the "Ion channel effects on neuron membrane potentials" KA passage.
I could not follow through what the 2nd paragraph meant.
I could not follow through what the 2nd paragraph meant.
A scientist is studying neurons in vitro to determine what occurs at a newly discovered ion channel. When many of these channels are opened, the membrane potential changes from -60 mV to -50 mV. The resulting membrane potential after opening many of these channels with a decreased extracellular concentration of sodium ions is -60 mV, with a decreased extracellular concentration of chloride ions is -50 mV, and with a decreased extracellular concentration of calcium ions is -50 mV.
Maybe I was not able to follow through what was going in and what was already in. Can someone break it down?
