Question

1.The action potential is characterized by: Bbl6epuTe oAMH OTBeT: a. Stable polarization of the membrane b. Changing the charge of the membrane under the action of subthreshold stimuli c. Polarization of the cell membrane in the absence of stimuli d. Changing the charge of the membrane under the action of threshold stimuli

Answer 1

The correct answer is d. Changing the charge of the membrane under the action of threshold stimuli.An action potential is a rapid change in the electrical charge across the cell membrane that occurs in response to a stimulus. It is characterized by a sudden depolarization of the membrane, followed by a repolarization back to the resting membrane potential. This process is triggered when the membrane potential reaches a certain threshold, typically around -55 mV. The action potential is essential for the transmission of signals in neurons and other excitable cells.
