1.) When a person has hyperkalemia, their extracellular potassium levels increase, making membrane potential more positive and causing the cell to get closer to depolarization.
2.) When a person is hyperglycemic, the increased glucuse causes inhibition of the ATP-sensitive potassium channel that channels K+ out of the cell. This increases the intracellular potassium levels in relation to the outside, causes membrane potential to become more positive and causes the cell to get closer to depolarization.
What in the world is going on here?
Increased extracellular potassium is making membrane potential more positive,
Decreased extracellular potassium is making membrane potential more positive.
How can both of these be true?
