During the propagation of a nerve impulse, the action potential results from the movement of
1. K+ ions from extracelular fluid to intracellular fluid
2. Na+ ions from intracellular fluid to extracellular fluid
3. K+ ions from intracellular fluid to extracellular fluid
4. Na+ ions from extracellular fluid to intracellular fluid
When neuron is resting, which of the following is false with respect to that
1. | It is not conducting any impulse |
2. | Axonal membrane is more permeable to potassium ions |
3. | Axonal membrane won't allow any flow of sodium ions across it |
4. | Membrane is impermeable to negatively charged proteins |
