    How don't neurons get enough K+ to balance out their inner negative charge?

    Na+/K+ pump is an ATPase Phosphate bond hydrolysis ΔG=−30.5 kJ/mol it pumps 3 Na+ and 2 K+ against their respective electrochemical gradients. this is a form of active transport and does not depend on the gradients unless the energy stored in a phosphate bond is comparable to the gradient...

    How don't neurons get enough K+ to balance out their inner negative charge?

    The membrane has negligible/leaky permeability to K+ at rest. K+ permeability increases AFTER the influx of Na+ Also if the membrane is fully permeable to K+ then it won't be at the resting membrane potential. K+ will move out as it is less concentrated outside the cell, this efflux causes...

    How don't neurons get enough K+ to balance out their inner negative charge?

    There are no contradictions, there is only a balance of polar opposites. Understand equilibrium and you will understand biology. yin and yang

    How don't neurons get enough K+ to balance out their inner negative charge?

    Na+ IS repelled by the excess of Na+ and other positive charges. Only you have to factor in permeability. Neurons are designed to maintain a negative resting membrane potential. Meaning they have channels that open only at specific threshold voltages. Extracellular signals at the synapse...
