Opening of sodium gates typically leads to

WebMultiple Choice Opening of sodium gates typically leads to A)repolarization of the plasma membrane. B)hyperpolarization of the plasma membrane. C)depolarization of the plasma membrane. D)drifting of plasma membrane voltage toward a more negative value. E)plasma membrane voltage returning to the resting membrane potential. Correct Answer: WebThe sodium/potassium pump requires energy in the form of adenosine triphosphate (ATP), so it is also referred to as an ATPase. As was explained in the cell chapter, the concentration of Na + is higher outside the cell than inside, and the concentration of K + is higher inside the cell than outside. That means that this pump is moving the ions against …

Na+ … Web17 de jan. de 2024 · The depolarization, also called the rising phase, is caused when positively charged sodium ions (Na+) suddenly rush through open voltage-gated sodium channels into a neuron. As additional sodium rushes in, the membrane potential actually reverses its polarity. WebVoltage-gated sodium channels have two gates (gate m and gate h), while the potassium channel only has one (gate n). Gate m (the activation gate) is normally closed, and opens when the cell starts to get more positive. Gate h (the deactivation gate) is normally open, and swings shut when the cells gets too positive. bixx sonnenstudio forchheim
