«Half the calories a brain burns go towards simply keeping the structure intact by
pumping sodium and potassium ions across membranes to maintain an electrical charge,» according to the video.
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.
For example, ATP1B1 encodes a sub-unit of the
sodium -
potassium plasma membrane
pump, which is essential for water
and ion transport.
Working together, they performed the crucial electrophysiological studies on the mutated
sodium -
potassium pump,
and the studies showed that the presence of the inserted positively charged arginine converts the
sodium -
potassium pump to an electroneutral
pump just like the acid
pump.
«The
sodium -
potassium pump and the acid
pump are very similar in many respects,
and this is crucial for understanding the perspectives of the research results,» says Professor Bente Vilsen.
Under pressure to name several possible future perspectives, Bente Vilsen mentions that the discovery of the electroneutral
sodium -
potassium pump also makes it possible to explore what an inability to produce current means for the development of the cells
and the occurrence of diseases in e.g. the brain
and kidneys, where the
sodium -
potassium pump plays a crucial role.
In a recently published study in Science, researchers from Aarhus University, KTH Royal Institute of Technology
and Stockholm University at SciLifeLab presented structural information on the
sodium -
potassium pump in its
sodium - binding state that is essential for our understanding of illness
and for the development of new medicines.
The heart muscle finds it a lot harder to
pump blood when the levels of
potassium and sodium are out of balance.
Each cell in the body has a
sodium:
potassium pump that regulates the balance of minerals inside
and outside the cells.
Due to the importance of the proper calcium / magnesium ratio in the body
and the function of the
sodium:
potassium pump, magnesium deficiency can lead to:
Dr. Justin Marchegiani: Except if it's low — if it's low, it'll bring it up much higher because you know, let's say your adrenals are really key at holding on to minerals
and if you're decreasing your mineral retention because the aldosterone that your adrenals make is low because of the adrenal dysfunction that's happening, you will pee out more minerals
and that — that's important for regulating blood pressure
and that's also important for their
sodium potassium pumps, so if we don't have enough high quality
sodium, those
sodium potassium pumps kinda that creates the gradient
and how things go in
and out of the cell, now if don't have adequate
sodium on board, that can definitely be a stressor for the body.
Restocking depleted muscle glycogen, optimizing immune function,
and replenishing the
sodium -
potassium pumps in your brain neurons
and exercised muscles all require significant energy expenditure.
If you cut your
sodium intake, then the Na / K
pump will stop working optimally
and potassium will start to accumulate in the extracellular fluid, leading to a bloated look.
Like with
sodium and potassium pumps, insufficient magnesium may prevent calcium
pumps from working.
