Sentences with phrase «charged ions flow»

As soon as these cells are exposed to light, the channels open and positively charged ions flow into the muscle cell, which then contracts.

Not exact matches

While electrons, with their negative charge, flow from one pole of the battery to the other (thus providing power for devices), positive ions flow the other way, through an electrolyte, or ion conductor, sandwiched between those poles, to complete the flow.
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.
Ion channels are biomolecules that allow charged atoms to flow in and out of cells, and they are an important work - horse in cell signaling, sensing, and energetics.
They use charge in the form of ions to carry energy and information — ion channels control the flow of ions across cell membranes.
Today's most popular rechargeables, lithium ion batteries, are made from negative and positive electrodes separated by an electrolyte through which positively charged lithium ions can flow back and forth.
TMEM16A is part of a protein family whose members facilitate the flow of negatively charged chloride ions or lipids across the cell membrane.
In this scenario, when an object moved in the neuron's preferred direction, excitatory impulses would reach the target neuron first, triggering positively charged sodium ions to flow into the cell — an excitatory current.
Memristors, however, incorporate both electron flow and ions — electrically charged atoms.
Unlike conventional SOFCs the BZY membranes allow the flow not of negatively charged oxygen ions toward the anode, but positively charged hydrogen ions, the opposite way, toward the cathode.
Nerve cells rely on ion channels and pumps to orchestrate the continual ebb and flow of charged particles across the cell membrane, which enables the electrical signaling that nerves use to communicate.
Rather than being evenly distributed, the nickel clumps together and blocks the channels, preventing the flow of ions and keeping the battery from charging.
When light is shone on the neuron, the channel opens up and allows electrical ions to flow into the cell; a bit like a battery being charged by a solar cell.
Most redox - flow batteries are based on metals, usually vanadium, in acidic media, and charge generation is based on ion - selective membranes separating the two electrolytes.
The flow of electrical charge and ions are controlled by the structure while the interface is charged, and the stronger binding of water molecules at the surface might explain why hematite dissolves more slowly than predicted.
A «flow battery» stores energy like the basic lithium ion battery in your laptop, but flow batteries have their electrolyte (the substance that acts as the medium for the charging and discharging of the battery) separated out of the battery cell in liquid - filled tanks.
Beyond the current charge level of the lithium - ion battery, this display also shows the real - time flow of energy.
Due to the vertical current flow, space charge accumulates at upper and lower cloud boundaries as a result of the effective scavenging of ions within clouds by droplets, creating conductivity gradients at the cloud edges (Nicoll & Harrison 2010).
Generally speaking, lithium - ion controllers define the current (in amps) at which the battery charges by measuring the battery's cell current and voltage, and then adjusting the current flowing in.
