-Figure 37.2 shows many proteins in a neuron membrane.The first protein on the left is a sodium-potassium pump.What would happen if this protein became blocked and thus unable to function?
A)The cell's membrane potential would not change.
B)The cell would hyperpolarize.
C)The cell would depolarize.
D)The potassium and sodium gradients would be eliminated.
