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

Answer 1

Filled answers:

At rest, the cell membrane of a neuron is 1. negatively.
2. Sodium-Potassium Pumps have actively transported more 3. sodium outside the cell, and more 4. potassium inside the cell. This creates a gradient the ions will later move along through 5. diffusion. Because the outside of the neuron is more 6. positively charged and the inside is more 7. negatively charged, a voltage difference of 8. -70 mV is created. This is called the resting membrane potential.

Letter choices used:
1 = F, 2 = G, 3 = A, 4 = B, 5 = D, 6 = E, 7 = F, 8 = I.
