No. The chain of reactions set off by an action potential either is or is not set off.

Would an action potential be possible without the presence of proteins?
No, proteins play a critical role in generating and propagating action potentials in neurons. Channels and pumps made of proteins are responsible for the movement of ions across the cell membrane, which is crucial for the changes in membrane potential that underlie an action potential. Without proteins, the necessary ion movements would not occur, and an action potential would not be possible.
Will a hyperpolarization graded potential lead to an action potential?
No, hyperpolarization graded potentials do not lead to action potentials. Hyperpolarization makes the membrane potential more negative, which inhibits the generation of an action potential by increasing the distance from the threshold potential needed to trigger an action potential.
What part of the neuron can conduct an action potential?
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
What is the regeneration of action potential called?
The regeneration of action potential is called "propagation." It involves the transmission of the action potential along the length of the neuron's axon.
What transmission of the depolarization wave along the neurons membrane?
Action potential

Without proteins, the necessary ion movements would not occur, and an action potential would not be possible.
What is the cause of the relative refractory period?
The Refractory period is when a second action potential is possible, but unlikely; second action potential only if the stimulus is sufficiently strong. The refractory period helps to prevent backflow of Sodium.
What was the effect of curare on eliciting an action potential?
It creates an action potential
What part of the neuron can conduct an action potential?
The axon of a neuron is responsible for conducting an action potential. This is made possible by the presence of voltage-gated ion channels along the axon membrane that allow for the propagation of electrical signals.
What is the primary feature of a neuron that prevents the action potential from traveling back from where it just passed?
The presence of voltage-gated sodium channels in the neuron membrane is the primary feature that prevents the action potential from traveling back, as these channels temporarily become inactivated after opening during depolarization. This inactivation prevents the movement of sodium ions back through the channel in the opposite direction.
Why does curare create an action potential?
Curare does NOT create an action potential. It binds to nicotinic acetylcholine receptors (which are primarily excitatory), and prevents the formation of an action potential.
Why does curare appear to generate an action potential?
It doesn't. I prevents an action potential from forming.
What transmission of the depolarization wave along the neurons membrane?
Action potential
Also called a nerve impulse transmitted by axons?
action potential
Can subthreshold stimulation cause an action potential?
No, subthreshold stimulation is not sufficient to trigger an action potential. The membrane potential needs to reach a certain threshold level for an action potential to be generated. Subthreshold stimulation only produces graded potentials that do not reach the threshold for firing an action potential.
What is the difference between a compound action potential and a single action potential?
A compound action potential is the summation of multiple individual action potentials from different neurons, resulting in a larger, composite response. A single action potential is the brief electrical impulse that travels down an individual neuron in response to a stimulus.
An electrical impulse moving down an axon is called?
An electrical impulse moving down an axon is called an action potential. This process involves the rapid depolarization and repolarization of the axon membrane in response to a stimulus, allowing for the transmission of signals along the neuron.
