A channels opens a postsynaptic membrane that causes a negative ion to enter the cell. What type of graded potential is this?
What events in a neuron membrane occur slowly when threshold potential is reached?   Opening of K+ channel activation gate   Closing of Na+ channel inactivation gate   Opening of the Na+ voltage-gated channel activation gate   Closing of Cl- voltage gated channels   Closing of K+ inactivation gate (More than one answer may be correct, please help in answering)
Which of the following statements is TRUE about the depolarization phase of action potential? Group of answer choices: Na-K pump initiates depolarization. Potassium ion channels quickly opens to allow efflux of ions. Depolarization is characterized by the movement of calcium ions out of the cell. Depolarization is primarily triggered by opening of sodium ion channels   asap pls
