When extracellular potassium is increased from 4 meq to 10 meq what will happen
Correct Answer: Increase in conduction of potassium
Description: If the extracellular potassium concentration surrounding a myocyte increases, then the potassiumgradient accross the cell membrane decreases, and therefore the resting membrane potential will become more positive. There fore increase in the conduction of pottasium increases Similarly, if extracellular potassiumdecreases, the resting membrane potential will be more negative.
