-70 mV - the resting membrane potential in most cells is approximately -70 mV - the resting membrane potential of the cell -70 mV - what is the value for the resting membrane potential for most neurons? -90 mV - the membrane charge value when there is no net movement of K+ into or out of the cell 1. blood glucose becomes high 2. pancreas releases insulin 3. insulin binds to receptors on target cells 4. cells take in glucose 5. blood glucose returns to normal - order of events in the body...
