Answer:D
Explanation:I just took the test and got it correct.
K+ channel opens, resulting potential -90mV
This is due to hyperpolarization.
<h3>What is hyperpolarization?</h3>
- Hyperpolarization is a change in a cell's membrane potential that makes it more negative (i.e. decreases).
- It results in increase in the potential difference across the membrane.
- K+ moves from the inside to outside as some potassium channels remain open and sodium channels reset. A period of increased potassium permeability results in excessive potassium efflux before the potassium channels close.
- K+ channels typically cause membrane potential to become more negative.
