What else can I help you with?
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?
Ion channels that are always open are called leak channels. They allow a continuous flow of ions across the cell membrane, helping to maintain the resting membrane potential of the cell.
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 are the differences between leak channels and gated channels in terms of their function and regulation in cellular physiology?
Leak channels are always open and allow ions to pass through the cell membrane freely, while gated channels can open and close in response to specific signals. Gated channels are regulated by various factors such as voltage, ligands, or mechanical stimuli, whereas leak channels do not require any specific signals to function.
How do marketing channels emerge?
Marketing channels always emerge from the demands of a marketplace.
Which ion channels open in response to a change in membrane potential?
voltage-gated ion channels
Are gated channels are always open?
Yes, it can a gated ion channel is opened when a signal molecule binds to a receptor protein causing the receptor protein to open the ion channel through the cell membrane and after this process the ion channel is closed once again to prevent various molecules to enter the cell.
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.
Why do marketing channels evolve?
As always, marketing channels were evolving in response to changing marketplace needs.
When an individual experiences hypothermia which leakage channel in cells of the sinoatrial node become less permeable and cause the heart rate to decrease?
sodium channels
