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
specific glycoproteins on red blood cells determines?
ABO blood type
proteins of cholera and tetanus bind to cell how?
by identifying specific carbs on proteins
sperm knows egg how?
by specific glycoproteins
