What else can I help you with?
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.
Would conduction speed of a nerve fiber be the fastest in a large or small myelinated fiber?
The conduction speed of a nerve fiber is fastest in large myelinated fibers. This is because myelin acts as an insulator, allowing for faster propagation of the action potential by saltatory conduction in large fibers compared to small unmyelinated fibers.
According to the all or none principle what would happen if a cell were depolarized twice the normal amount needed to produce an action potential?
If a cell were depolarized twice the normal amount needed to produce an action potential, it would still only produce a single action potential. The all-or-none principle states that once the threshold for an action potential is reached, the neuron will fire with a fixed amplitude and duration regardless of the strength of the stimulus.
What would most likely happen to the action potential, if a neuron lost its myelin sheath?
The actional potential would not reach the axon terminals.
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
What is the magnitude amplitude of an action potential?
The amplitude is about +35 to +40 Millivolts I believe this is incorrect, as this would only raise the resting membrane potential from -70mV to -35 or -40. An action potential needs to raise the membrane potential from -70 mV to +30 mV, so the amplitude needs to be 100 mV.
Which of the following would have the fastest conduction of an action potential?
myelinated, large diameter fibres
How white tiger to conserve it?
White tigers are freaks/mutants that are propagated in captivity for novelty value. They would not survive in the wild and do not need conservation - indeed, many people would argue that they should not be propagated from.
What is the amplitude of an action potential?
The amplitude is about +35 to +40 Millivolts I believe this is incorrect, as this would only raise the resting membrane potential from -70mV to -35 or -40. An action potential needs to raise the membrane potential from -70 mV to +30 mV, so the amplitude needs to be 100 mV.
Why does action potential's move through axons in only one direction?
the axons and dentrites would get mixed up and the brain would be thinking in two ways and we would be confused to which one was which
How would you use the word would in the sentence?
The word 'would' is a verb, an auxiliary verb used with a main verb to express a preferred course of action, an action that might occur, or the consequences of a potential action.Example uses:Jim would like some iced tea.The auxiliary verb 'would' expresses preferred course of action for the verb 'like'.A trip to Hawaii would be expensive.The auxiliary verb 'would' expresses the consequences of a potential action of the verb 'be'.Additional examples:I would answer this question if I could!I'm just not certain that that wood would be satisfactory for this project.I would go to the theme park with you on Saturday.
How did the action potential generated with the unheated rod compare to the generated with the heated rod?
Heat information is conducted through neurones. Higher frequency action potentials are perceived in the brain as a hotter stimulus. So the heated rod would have sent higher-frequency action potentials than the cool rod would have.
