Not exact matches

In this case, over time, amino acids in three different sodium channels found in nerves and muscle changed, allowing select snakes to resist the numbness and paralysis typically brought on by the toxin.

Bound to the cell membrane, Na ± K+ATP ase uses the energy of adenosine triphosphate (ATP) molecules to pump sodium out of the cell and potassium into the cell, maintaining a charge gradient that allows ions to flow through open channels.

The selectivity filter is the functional unit that allows K + channels to distinguish potassium (K +) and sodium (Na +) ions.

Researchers have known for decades that some microorganisms, such as single - celled green algae, have proteins that respond to light by opening a channel in the microbe's membranes, allowing the passage of electrically charged ions (such as calcium and sodium).

In cells from sick hearts, these channels often don't inactivate properly, allowing for excess sodium entry and a build - up of calcium, which ultimately promotes abnormal heart rate (arrhythmia) and symptoms of heart failure.

It acts by binding to specific receptors and allowing sodium (Na +) or calcium (Ca +) to move into brain cells through channels.
