the rising phase, which ion channel is responsible for action potential returning to its resting Vm, and why? Na* channels, because positive Na* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise Vm Na channels, because positive Na* ions are at higher concentration inside the axon than outside, and so they leave the axon and raise Vm O K* channels, because positive K* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise V m K* channels, because positive K* ions are at higher concentration inside the axon than outside, and so they leave the axon and lower V.

4.3. After the rising phase, which ion channel is responsible for action potential returning to its resting V and why? Na channels, because positive Na* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise V O Na* channels, because positive Na* ions are at higher concentration inside the axon than outside, and so they leave the axon and raise V, m O K* channels, because positive K* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise Vm U K* channels, because positive K* ions are at higher concentration inside the axon than outside, and so they leave the axon and lower Vm
