Nav1.7 contains four peripheral voltage - sensor domains (VSDs) that surround and control a central ion pore domain that
allows sodium ions to enter and initiate action potentials in sensory neurons.
Like a type of door, sodium channels
allow sodium ions to flow into nerve cells through tiny pores.
When a cell receives a stimulus, the cell opens gates that
allow sodium ions to rush into the cells and potassium ions to rush out.
Not exact matches
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.
When exposed to capsaicin, these receptors open to
allow in
sodium and calcium
ions, causing the receptors to transmit that hot signal to the brain.
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).
Incorporating the anode into a
sodium -
ion battery
allowed it to perform at 83 percent capacity over 900 cycles.
