Resting Membrane Potential Flashcards
energy that results from seperation of charges (also called potential difference ) is?
voltage
voltage or electrical potential energy gained by seperating opposite charges across a membrane when at rest is?
RMP resting membrane potential
in the RMP theory, the inside of the cell is _________ than the outside fo the cell
more negative
Na+-K+ATPase Pump creates a gradient for both ______________?
Na+, K+
sodium out is greater than sodium in and potassium in is greater than potassium out is the gradient created by?
Na+-K+ATPase Pump
1 Na+-K+ATPase Pump cycle =
3Na+ OUT 2K+ IN
Na+ channels are __________, this stops ________________________?
normally closed, sodium from moving easily into cell.
K+ channels are _________ so that ________ can slowly leak out.
normally slightly open, potassium
the net movement of Na+ and the leaking of K+ to the outside of the cell causes?
a potential difference OR VOLTAGE across the membrane
resting membrane potential for cells generally range from?
-20mV to -200mV
how many ways can the body create RMP?
3, sodium channel, potassium channels, sodium potassium atpase pump
resting membrane potential is a baseline TorF
True, the changes create voltage
charge + concentration =
electrochemical gradient
NA+ wants and K+ wants
electro in and chemical in/electro IN chemical out
the glycocalyx is made up of?
sugary coat, carbohydrates attached to proteins and lipids outside cell membrane
