Imagine you genetically engineered a neuron to produce voltage-gated Na" and K channels that opened at the same time in response
to a change in voltage. How would that change the recording shown in the figure? eacitation 1 4 Resting potential A) Threshold values would increase B) The peak voltage would be higher. C) The peak would occur over a longer period of time. D) The period of hyperpolarization would be longer. E) No action potential would be generated.
As we know the voltage gated Na and K channels has specific roles in the generation of action potential. When both the channels are opened at the same time sodium will move inside and potassium will move outside no action potential would be generated.
At the peak of action potential , area of the neuron is about 40 mV positive. Now when the voltage becomes positive , sodium channels close and the potassium channels open.
When the potassium channels open , they cause the potassium ions to rush out of the cell thus causing the voltage to become negative again.
Hence E) No action potential would be generated is the right answer.
Humus, which ranges in color from brown to black, consists of about 60 percent carbon, 6 percent nitrogen, and smaller amounts of phosphorus and sulfur
