Question

In a neuron with a resting membrane potential of -85 mV, which ion LEAST contributes to the generation of the value of resting potential?

Choose one answer:
a. Potassium
b. Calcium
c. Chloride
d. Sodium
e. This cannot be stated

Answer 1

e. This cannot be stated.

Step-by-step explanation:

Potassium , Calcium , Chloride and Sodium are the ions that contributes to the generation of the value of resting potential. There is no example of such an ion which causes the least contributes to the generation of the value of resting potential so that's why we choose option E. The resting membrane potential (RMP) occurs due to changes in the permeability of membrane for potassium, sodium, calcium, and chloride, which leads to the movement of these ions across it.
