Question

8 at resting potential, the ion distribution inside and outside of a neuron is such that there is a more __________ charge on the inside, and a more __________ charge on the outside of the cell. a. positive, positive b. positive, negative c. negative, negative d. negative, positive 9 how does repolarization differ from depolarization? a. during repolarization, the positive ions are moving back to the outside of the membrane. b. during repolarization, the action potential is being propagated down the axon. c. during depolarization, the positive ions are moving back to the outside of the membrane. d. during repolarization, the negative ions are moving back to the outside of the membrane.

Explanation:

For the first question, at resting potential, there is a negative charge inside the neuron and a positive charge outside due to the unequal distribution of ions like sodium and potassium. For the second question, during repolarization, positive ions move back outside the membrane to restore the resting - potential state.

Answer:

1. d. negative, positive
2. a. During repolarization, the positive ions are moving back to the outside of the membrane
