if the membrane is perfectly selective for potassium ions. You also learned that the slope of the line should have a value of 58 mV for a 10-fold concentration difference at room temperature (rising ...

Ion channels are protein structures embedded in cell membranes that allow charged ... focused on the mammalian BK ("big potassium") channel, which facilitates the flow of potassium ions out ...

I HAVE read with interest the recent communication of Salminen 1 on the effect of hydrogen ions on tho differential rates of migration of sodium and potassium ions. I believe this may relate to an ...

Neurons send signals via action potentials, which involves a rapid exchange of ions across tiny conduits in the membrane called ... change in a specific potassium ion channel speeds up their ...

Calcium ions can trigger a BK channel to open its central passage or "pore," allowing a massive flow of potassium ions out ... related molecules in the cell membrane can influence BK channel ...
