Question 11Place the following events of an action potential in the correct order: 1. Na channels are inactivated and K channels open. 2. The cell temporarily hyperpolarizes. 3. The cell depolarizes as Na diffuses into the cell. 4. A graded potential brings the trigger zone to the threshold voltage. 5. The cell returns to resting ion permeability and resting membrane potential. 6. The cell repolarizes as K diffuse out of the cell. 7. Na channels open. 8. The K channels close. + + + + + + 4 – 7 – 3 – 1 – 6 – 2 – 8 – 5 5 – 8 – 2 – 6 – 1 – 3 – 7 – 4 4 – 7 – 6 – 1 – 3 – 2 – 8 – 5 4 – 7 – 3 – 1 – 6 – 8 – 2 – 5 4 – 7 – 3 – 8 – 6 – 2 – 1 – 5 0.5 / 0.5 pts Question 12The below diagram is for a single action potential; which of the followingbest describes #4 ?
