Graph showing ventricular action potential with delayed repolarization by potassium channel blockade. Potassium-channel blockers comprise the Class III antiarrhythmic compounds according to the Vaughan-Williams classification scheme. These drugs bind to and block the potassium channels that are responsible for phase 3 repolarization. Therefore, blocking these channels slows (delays) repolarization, which leads to an increase in action potential duration and an increase in the effective…

Octopuses Edit Proteins to Beat the Cold by ScienceNow: J. Rosenthal et al have demonstrated that the Antarctic octopus edits its RNA at nine sites, changing the amino acid sequence of potassium channels and enabling it to offset the inhibition of nerve cell firing by cold. #Octopus #Antarctica #Joshua_Rosenthal #RNA_Editing

Education: Big Conductance Potassium Channels.   So today we continue on the potassium channel journey and today we do the calcium activated potassium channels There are small conductance intermediate and big conductance calcium activated potssium channels called the SK channels and theBKchannels.  They are so called because of their small single channel conductance in the order of 10 pS(picoseimens = unit of electrical conductance The SK channel family contains 4 members -SK1SK2SK3 andSK4…

PDB-101: Potassium Channels

The resting membrane potential of minus seventy volts is maintained by a sodium/potassium transporter that transports sodium ions out of the cell and potassium ions in. Voltage gated sodium and potassium channels are closed. In response to a nerve impulse, some sodium channels open, allowing sodium ions to enter the cell. The membrane starts to depolarize; in other words, the charge across the membrane lessens. If the membrane potential increases to the threshold of excitation, all the…

This diagram shows how sodium and potassium ions are pumped through protein channels. The sodium ions are pumped out of the cell, while potassium is pumped into the cell. The movement of these ions creates resting potential and action potential.

This image shows a top view of potassium ions (purple) moving through potassium channel.
