Question

part 1: key terms put these in order before moving on to part 2(this should form a loop) (each should be inside its own shape)
sodium\potassium pump
potassium rushes out of the cell
depolarization
repolarization
sodium rushes into the cell
resting membrane potential
potassium channels open
sodium channels open
stimulus

part 2: action words ( add these shapes. connect these to the key terms as descriptions after your loop from part 1 is complete) (can be used more than once if needed)
moves 3 sodium out for every 2 potassium in
this causes sodium channels to open
the inside of the cell now becomes more positive than the outside
the outside now becomes more positive than the inside
uses atp to create the resting membrane potential
the majority of sodium ions are outside the cell and the potassium inside
the protein channel changes shape and opens. (use twice)
the ions move by simple diffusion and by attraction to the opposite charge (twice)
before the signal begins the outside of the cell is more positive than inside the cell

Explanation:

The process starts with the resting membrane potential where the outside of the cell is more positive than the inside. A stimulus causes sodium channels to open. Sodium rushes into the cell making the inside more positive (depolarization). Then potassium channels open, potassium rushes out of the cell, making the outside more positive again (repolarization). The sodium - potassium pump moves 3 sodium out for every 2 potassium in using ATP to re - establish the resting membrane potential.

Answer:

Resting Membrane Potential, Stimulus, Sodium Channels Open, Sodium rushes into the cell, Depolarization, Potassium Channels Open, Potassium rushes out of the cell, Repolarization, Sodium\Potassium Pump, Resting Membrane Potential
