What would happen to the neuron if the Na- K ATPase activity was completely inhibited? O a. The resting potential wouldn't be restored after the action potential Ob. Repolarization of the membrane wouldn't appear. c. The resting potential would be restored too fast after the action potential. Od. The action potential couldn't be generated.

2. Neuron during an action potential: a. What triggers the first action potential (which ion)? b. What is the typical threshold potential of a neuron? c. The calculated equilibrium potential of Na+ (EN) is approx. +60mV (calculated). Explain how this is related to the rising phase of an action potential (depolarization). d. The calculated equilibrium potential of K+ (EK) is approx. -90mV. Explain how this is related to the falling phase (repolarization). e. Direction of Nation movement (influx/efflux). f. Direction...
