At rest, which ion has both forces aligned?

Select one:

a. K+

b. Na+

c. Na-

d. K-

e. Cl+

Expert Solution

K+ is the right answer.

Explanation:

Potassium ion is found on the inner side of the plasma memebrane as compared to the sodium ion in resting stage. But as the action potential generated, there is found movement of sodium ion inside the membrane. Then during depolarisation, potassium ion moves outside to reduce the membrane potential. After that sodium pottasium pump maintain the concentration via ATP hydrolysis.
