Question

At rest, the cell membrane of a neuron is 1._ .
2._ have actively transported more 3._ outside the cell, and more 4._ inside the cell. This creates gradient the ions will later move along through 5._ . Because the outside of the neuron is more 6._ charged and the inside is more 7._ charged, a voltage difference of 8._ mV is created. This is called the resting membrane potential.


A. Sodium
B. Potassium
C. +30
D. Diffusion
E. Positively
F. Negatively
G. Sodium-Potassium Pumps
H. -55
I. -70
J. Polarized

Answer 1

1. J (Polarized)
2. G (Sodium-Potassium Pumps)
3. A (Sodium)
4. B (Potassium)
5. D (Diffusion)
6. E (Positively)
7. F (Negatively)
8. I (-70)

Completed sentence:
At rest, the cell membrane of a neuron is polarized. Sodium-Potassium Pumps have actively transported more sodium outside the cell, and more potassium inside the cell. This creates a gradient the ions will later move along through diffusion. Because the outside of the neuron is more positively charged and the inside is more negatively charged, a voltage difference of -70 mV is created. This is called the resting membrane potential.
