At rest, most cells are more ______ inside the cell than outside the cell

negative

Muscle and neuron cells are excitable neurons which means….

they depend on a change to their electric potential

If a cell needs to return back to its resting potential, the ________ is critical

sodium potassium pump

The sodium potassium pump is initially open to the intracellular side, leaving binding room for….

three sodium ions

After the three sodium ions bond, the channel protein is ______ by an ATP phosphate

phosphorylated

What does it mean to be phosphorylated

the proteins configuration is changed (shape is changed)

After the sodium ions are pushed to the extracellular side, two _______ ions bind in the pump

potassium

The ATP phosphate is _______ from the pump, and the pumps configuration changes to the ________ side

released, intracellular

A sodium potassium pump is a great example of ______ ______ because it keeps putting more sodium outside when there is already a high concentration of sodium, and the same thing for potassium
