The ion that is being moved out of the cell according to Model 1 is Sodium ions (Na+)
a. How many of these are being moved out is Three
b. Is this ion positively or negatively charged is Positively charged
2. The ion is being brought into the cell according to Model 1 is Potassium ions (K+)
a. The number of these that are being moved is Two
b. Positively charged
The sodium-potassium pump is essential for maintaining the resting membrane potential, which is the voltage difference across the cell membrane. The sodium-potassium pump actively transports ions against their concentration gradients, which requires energy.
So,If the sodium-potassium pump stops working, the resting membrane potential will depolarize, meaning that the inside of the cell will become less negative and the outside of the cell will become less positive. This can lead to cell death.
