Explanation:
The resting membrane potential (-70 mV) is primarily established and maintained by the Na+/K+ ATPase pump, which actively transports 3 Na+ out and 2 K+ into the cell, creating an electrochemical gradient. Additionally, the membrane is much more permeable to K+ than to Na+ due to K+ leak channels. K+ diffuses out of the cell down its concentration gradient, leaving the inside negatively charged.
