What should be the value of Vce if the base terminal of a transistor is open?
It would be zero because there is a leakage.
What changes occur to voltage-gated Na and K channels at the peak of depolarization?
Inactivation gates of voltage-gated Na+ channels close, while activation gates of voltage-gated K+ channels open.
Can capacitors charge on an open circuit?
No. Capacitors need current to charge or discharge. In an open circuit, current is impossible, so they will stay at the last known charge, depending on the amount of leakage current.
What causes collector current to flow when the emitter current is zero?
A: All transistor experience some kind of leakage with the one of the three termianal open. it called Iceo.
What is the source of leakage current in a transistor?
The current of the minority charges (collector region) is the source of the leakage current. At higher temperature, this leakage current increases due to increase in thermal energy.
What is it that ion channels may be always or have?
They may be always open or they may have close gated channels
Are the pores of ion channels always open?
Depends on the ion channel. Heart muscle cells have both leaky channels that are open all the time and other channels that only open at certain voltages across the cell membrane.
Ion channel that are always open are called?
leak channes
What channels are open during depolarization and during repolarization?
During depolarization Na channels are open During repolarization K channels are open
Was the Men's US Open tennis tournament on TV?
yes, it should be around all the sports channels. they always have the us open on tv
What passive channels are likely found in the membrane of olfactory receptor?
Answer this qOlfactory Receptor: Na+ ion channels Pacinian Corpuscle: K+ leakage channels Free Nerve Ending: Na+ ion channeluestion…
How do marketing channels emerge?
Marketing channels always emerge from the demands of a marketplace.
What happens to the neuron if sodium channels do not open?
causes chemically gated sodium channels to open
Which ion channels open in response to a change in membrane potential?
voltage-gated ion channels
When the alpha subunit of the G protein is activated it can stimulate ion channels to?
open and close channels
What is the open or close in response to binding specific molecules?
Chemically-gated channels
What helps maintain the resting potential of a neuron?
During resting potential, the Sodium-Potassium pump is inactive. Therefore, it is indirectly responsible for the resting potential. However, Potassium diffuses outside the membrane via "leakage" channels, and causes the resting potential.
