Resting membrane potential is maintained by the Na+/K+ pump which brings:
a. 2 potassium ions into the cystol and 3 sodium ions into extracellular fluid
b. 2 potassium ions into the cystol and 2 sodium ions into extracellular fluid
c. 3 potassium ions into the cystol and 3 sodium ions into extracellular fluid
d. 3 potassium ions into the cystol and 2 sodium ions into extracellular fluid
