Question

The resting membrane potential is maintained by

• A. Ion leaks
• B. Neurotransmitters
• C. Ion pumps
• D. Both (a) and (c)

Answer 1

Answer: (D)

Both (a) and (c)

Voltage-gated potassium channels are either open or closed. There are three main events during an action potential: A triggering event occurs that polarizes the cell body. This signal comes from other cells connecting to the neutron, and it causes positively charged ions to flow into the cell body.

So, the correct option is 'both (a) and (c)'.
