How is gradient of ions maintained in the mitochondria?
By the action of electrons going down the electron transfer chain the energy is provided to pump H + into the outer lumen of the mitochondria creating the concentration gradient for H + to come down it's concentration gradient through the ATP synthase.
How does a cell maintain differences in concentration of certain ions on either side of the plasma membrane?
Cells maintain unequal concentrations of ions on opposite sides of a cell membrane through active transport.
What will most likely happen if a toxin causes the hydrogen ion pump to stop moving H ions outside the mitochondrial membranes of the bird's cells?
Then there will be no build up of protons in the outer lumpen of the mitochondria. Without a heavy concentration of hydrogen ions ( protons ) there there will be no moment of hydrogen ions down their concentration gradient through the ATPase pump and no ATP generated.
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
Is Na K pump active or passive?
In biology, an ion transporter, also called an ion pump, is a transmembrane protein that moves ions across a plasma membrane against their concentration gradient, in contrast to ion channels, where ions go through passive transport.
What is the active transport mechanism by which cells pump sodium and potassium ions against the concentration gradient.?
sodium-potassium pump

What will most likely happen if the hydrogen pump protein in photosystem 2 does not move H ions into the thylakoid?
Well, not enough gradient will be built up so hydrogen comes down it's concentration gradient through the synthase and synthesizes ATP. Also NADPH will be adversely affected.

Active transport pump that helps move materials form low to high concentrations?
Thesodium-potassium pump uses active transport to move 3 sodium ions to the outside of the cell for each 2 potassium ions that it moves in.
Is lon pumps an example of passive transport?
No, it is an example of active transport. Ion pumps, such as a sodium or potassium pump, use ATP for energy and pump ions across a membrane. The pumps are necessary because the ions are going against the concentration gradient (Low concentration to high concentration. Therefore, ion pumps are an example of active transport

Which pump transports ions against their concentration?
active transport pump
Proceeds Against a concentration Gradient requires a carrier?
Solute pump

The sodium- potassium pump pump moving Na+ ions out and K+ ions in
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
