What happens to the resting membrane potential if ATP was deplete...
All active transportation of ions would stop and ions would be allowed to run down their concentration gradients, eventually reaching equilibrium. At this stage there would be no more electrochemical potential difference across the cell mem... Read More »

Which ion actively transported through the cell membrane to estab...
The answer is sodium (Na) At the normal resting potential, the cell must bail out sodium ions that leak in and recapture potassium ions that leak out. The "bailing" occurs through the activity of an exchange pump powered by ATP. This pump's... Read More »

All cells (including neurons) have resting membrane potentials. The ionic environment inside a cell differs from the ionic environment outside the cell. This difference is maintained by special ion pumps that are embedded in the cell membra...

The resting membrane potential is important because it maintains a 'ready state' for the cell to fire. Without the resting membrane potential there would be no driving force for ions like sodium to enter the cell; and if this doesn't happen...

The resting membrane potential difference between the inside and the outside of the cell is the result of selective permeability of the cell membrane and the active transport of ions into and out of the cell. Almost all cells have a potenti...

1) Yes, K+ goes out as Na+ goes in 2) no 3) no 4) They're not passive during action potential, more active really (refer to link) 5) decrease 6) increase Here's a good animation on this stuff for finer details: http://highered.mcgraw-hill.c...

B. more negative than its outside This is established by the concentration gradients and electrochemical gradients of Na+ and K+ set forth by the sodium/K+ pump. The resting potential inside the neuron is -70 mV
