    CNCORA 6 of 10 > Action potentials in neurons involve opening and closing of voltage-gated Nat and K ion channels. Place the events of an action potential in order, starting and ending with a cell at its resting membrane potential. Resting state Return to resting state Answer Bank A graded potential brings the membrane to threshold potential. Fast Na+ and slow K* channels are activated. Nat rushes into the cell, causing membrane depolarization. K channels close slowly, resulting in hyperpolarization....

    What is a resting potential? Is it positive or negative? The resting potential is mainly due to the main _____-charged large molecules stuck inside the neuron. The Na+/K+ pump pushes Na+ _____ of the cell and K+ ____ of the cell (in or out for each ion) Where is K+ concentrated, inside or outside of the neuron? Where is Na+ concentrated, inside or outside of the neuron? The action potential starts with an rise in membrane voltage. This is due...

    The fixed pattern of changes in membrane potential during an action potential is coordinated by the sequential opening and closing of voltage-gated ion channels. Can you identify the status (open/closed) of the voltage-gated Na+ and K+ channels during each phase of an action potential? Drag the appropriate labels onto the graph to indicate the status (open or closed) of the voltage-gated Na+ and K+ channels during each phase of an action potential. Labels may be used once, more than once,...

    This time you get into a snail brain neuron that is completely quiet. The cell doesn't even begin to fire action potentials when you inject depolarizing current, so you question yourself if you are actually in a neuron. Nevertheless, you briefly hyperpolarize thecell, and right after the hyperpolarization stops, the cell fires a few action potentials that have a quite large amplitude and then the cell becomes quite again. What could be going on here? Your traces kind of look...

    During the propagation of an action potential, what would be the effect of a mutation in the voltage-gated Na+-channels that does not allow “inactivation” phase to occur, such that these channels go directly from open to closed conformations? a) The neuron with the mutant Na+ channels will start letting in calcium ions and generate a calcium-based action potential that is stronger than the sodium-based action potential. b) The neuron with the mutant Na+ channel will exhibit a reverse electrochemical gradient...
