What results stay the same in an experiment?
controlled results stay the same in an experiment
How can you ensure the accuracy of your results which conducting a scientific investigation?
Check if the results are valid
What are the results of can water float on water?
The results of can water float on water is that the water builds a ocean.
Why is it important to report experimental results honestly even when the results go against your hypothesis?
k
What is the results of white candles burn faster than color candles?
I haven't seen the results of the project.
Is IPSP is associated with hyperpolarization?
yes, IPSP are associated with hyperpolarization because it inhibits Action Potentials from occurring and by doing so the neuron becomes hyperpolarized again
Inhibitory postsynaptic potential is associated with what?
An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential.
During an action potential hyperpolarization beyond more negative to the resting membrane potential is primarily due to?
Potential hyperpolarization are more negative to the resting membrane potential because of voltage. This is taught in biology.
What change in membrane potential depolarization or hyperpolarization triggers an action potential?
despolarization
What is the falling phase of action potential?
Hyperpolarization (the membrane potential becomes more negative)
What is the result of inhibitory neurotransmission on the postsynaptic membrane?
Hyperpolarization of the membrane. This inhibits action potential generation.
Do neurotransmitters always cause hyperpolarization of the postsynaptic membrane?
No, many neurotransmitters cause the postsynaptic membrane to be depolarized.
How is the K transmembrane flux when neurone hyperpolarizes?
The potassium ion channels in the cell open with hyperpolarization (injecting a negative current to take the cell potential more negative than Ek) The potassium ion channels in the cell open with hyperpolarization (injecting a negative current to take the cell potential more negative than Ek)
What is the hyperpolarization that occurs after repolarizing phase of action potential?
Hyperpolarization occurs because some of the K+ channels remain open to allow the Na+ channels to reset. This excessive amount of K+ causes hyperpolarization so the Na+ channels open to bring the potential back up to threshold.
Which ion is responsible for hyperpolarization?
potassium ions as they try to reach their equlibrium potential (-90mV) making the membrabe more negative and away from threshold
What Hyperpolarizing membrane potential occurs in the postsynaptic membrane of a synapse?
Hyperpolarization means that the membrane potential becames more negative than the resting potential. This means that it is more difficult for an action potential to be triggered at the postsynaptic membrane. This occurs at inhibitory synapses. Hyperpolarization can be achieved by increasing the permeability of the membrane to potassium or chloride ions. If potassium permeability is increased more potassium ions will leave the cell, down their concentration gradient; if chloride permeability increases chloride ions will enter the cell down their concentration gradient. Both movements will make the inside of the cell more negative ie they will cause hyperpolarization.
What is hyperpolarization of a dendrite by a neurotransmitter called?
According to Biologists, the hyper polarization of a dendrite by a neurotransmitter is known as an inhibitory postsynaptic potential (IPSP).
