What salts or minerals come from rocks?
Examples: sodium chloride, potassium chloride, sodium phosphates, sodium nitrate etc.
In the human body where does the energy for the sodium potassium pump come from?
The energy for the sodium-potassium pump in the human body comes from the hydrolysis of ATP (adenosine triphosphate) molecules. This process provides the necessary energy to move sodium ions out of the cell and potassium ions into the cell, against their concentration gradients, to maintain the cell's electrochemical balance.
Ions used to establish a resting potential?
Potassium and sodium determine the a cell's resting membrane potential. The equilibrium potential (the voltage where no ion would flow) for sodium is about +60 mV while that for potassium is usually around -80 mV, but because the resting cell membrane is approximately 75 times more permeable to potassium than to sodium, the resting potential is closer the the equilibrium potential of potassium. This is because potassium leak channels are always open while sodium come in through voltage gated or ligand gated channels.
What elements have a smaller density than water?
Most don't, but a few do. Na and K come immediately to mind ie the Alkali Metals.
How does the sodium potassium pump operates?
The sodium-potassium pump functions much like a revolving door. Its main job is to keep sodium ions (NA+) outside of the cell and keep potassium ions (K+) inside of the cell. With the addition of energy from an ATP molecule, the sodium potassium pump moves three sodium ions out of the cell and moves two potassium ions into the cell with each turn. The goal of this process is to return, or keep, the cell at a resting state, or resting potential.
What health problems do Siamese cats have?
They don't have any health problems. Only that their nose and eyes sometimes get black hard chunks in them but it is easily to come out.
What harm can result from bullying?
its come to life threating health problems
What caused widespread health problems in the mid 1980s and for years to come in northeastern Kazakhstan?
Nuclear Test Site in Semipalatinsk caused major environmental and health problems.
What are the health issuse campared to obesitiy?
Health issues that come from obesity, include diabetes, heart problems, and problems with circulation. A person that is obese may also have fatty livers, and problems with kidney function.
Where does the sodium potassium release potassium ions?
The "fast" voltage-gated sodium channels open at -55 mV and close at about +60 mV. I found your question by attempting to find an answer to its second part which is "when [do]...potassium channels open..." and I have yet to find the answer to this myself! There are lots of graphs in physiology books which indicate it is at a voltage very close to that of the sodium channel but I have yet to find an actual figure! The important thing to know is that the potassium channels open at a similar time but are much slower at allowing potassium to flow out of the cell. The effect is that the influx of sodium rapidly brings the resting membrane potential from it's threshold potential of -55 mV to its peak of about +60 mV, at which point they close and become refractory. The slower potassium efflux then "catches up" and brings the membrane potential back down towards its resting value and actually causes a small over-shoot known as hyperpolarisation. The net change in cytosol concentration of the ions is minimal and quickly reversed by the magnificent Sodium-Potassium-ATPase. If you come across the answer to the opening voltage of the potassium channels, please let me know!
Where does molten carbonate come from?
Sodium carbonate can be made by the Solvay process from brine (sodium chloride) and limestone (calcium carbonate). In the US there are large deposits of a mineral called Trona which is sodium bicarbonate carbonate, and it is obtained from that. Potassium carbonate is made by electrolysis of potassium chloride which is found as mineral Sylvite, which gives potassium hydroxide which is then carbonated with CO2. See wikipedia entries for Solvay Process, Trona, and Potassium Carbonate
Where did Sodium's chemical symbol come from?
Sodiums chemical symbol is 'Na'. 'Na' is the initials of the Latin word for sodium, which is ' NADIUM'. Similarly, Potassium (K) is from Latin for 'KALIUM'.
