What is ion exchange?
oin exchange
Which channel maintains the concentration gradients of ions across a neuronal membrane?
The sodium- potassium pump pump moving Na+ ions out and K+ ions in
Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?
Most animal cell membranes have proteins that pump ______ ions out of the cell and potassium ions into the cell
Is the movement of ions from an area of greater concentration to one of lesser concentration an example of osmosis?
The movement of ions/molecules from an area of greater concentration to an area of lesser concentration is called diffusion.Osmosis is a type of diffusion, which refers specifically to the movement of the solvent (usually water).
What does the proton pump use to move ions?
Ion pump proteins
The proton pump involves the movement of what?
Hydrogen ions (H+).
What ions are pumped in and out of cell through the sodium potassium pump?
3 sodium ions go out and 2 potassium ions go in
What is ion exchange?
oin exchange
Name two substances which are moved by active transport through membranes?
Sodium and Potassium. There is something called a sodium-potassium pump which transports 3 ions of Na+ out of the cell and 2 ions of K+ into the cell. This is facilitated by the breakdown of ATP to provide energy.
Which channel maintains the concentration gradients of ions across a neuronal membrane?
The sodium- potassium pump pump moving Na+ ions out and K+ ions in
How do ions and electrical charges play a role in communication with the muscle?
Ions and electrical charges, such as the potassium and sodium pump allow for the movement of messages along a neuron and that specific neuron (in this case motor) alerts the muscle to move.
In the sodium potassium pump sugars and amino acids or other molecules are brought through the membrane along with sodium ions through?
Coupled Channels
Which ions are exchanged in a sodium potassium pump?
3 sodium ions for 2 potassium ions.
What does the potassium pump usually pump?
K+ ions only.
Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?
Most animal cell membranes have proteins that pump ______ ions out of the cell and potassium ions into the cell
Is the movement of ions from an area of greater concentration to one of lesser concentration an example of osmosis?
The movement of ions/molecules from an area of greater concentration to an area of lesser concentration is called diffusion.Osmosis is a type of diffusion, which refers specifically to the movement of the solvent (usually water).
Which pump transports ions against their concentration?
active transport pump
