Q4.3. After the rising phase, which ion channel is responsible for action potential returning to its resting Vm, and why? O Na* channels, because positive Na* ions are at higher concentration outside the axon than inside, and so they enter the axon and raise Vm 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 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 K* channels, because positive K* ions are at higher concentration inside the axon than outside, and so they leave the axon and lower

Thanks Ion Extracellular Concentration (mM) Intracellular Concentration (mM) Na+ 440 50 K+ 20 400 Cl- 560 52 Ca++ 10 1 What is the effect of the addition of extracellular TTX and TEA on equilibrium potential? TTX blocks K channel, and TEA blocks Na Channels. No change in the equilibrium potentail. TTX blocks Na channel and TEA blocks K Channels. The equilibrium potentials become less positive TTX blocks Na channel and TEA blocks K Channels. The equilibrium potential becomes more positive for both TTX blocks Na channel and TEA blocks K Channels. No change in the equilibrium potentail. TTX and TEA blocks Na channel.
