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!
Is alum the same thing as aluminum chlorohydrate?
Potash alum is another name for potassium alum. Alum is a class of molecular compounds, and included in the class is potassium alum. So, they are not the same thing, but yet very similar in that potash alum is a member of the alum class.
How does a neuron restore a membrane potential following the generation of an action potential?
The hyperpolarization of the membrane potential relative to the resting potential (the undershoot) causes voltage-dependent Potassium conductance (and any Sodium channels not yet inactivated) to turn off, allowing the membrane potential to return to resting level.
How does bohrs model differ from todays?
Bohr's atomic model depicts the electron shells and orbitals as being two dimensional, staying the exact same distance away from the nucleus the entire time. Today, we know that electron orbits are three dimensional, and at best can only say where the electron in a given orbital is most likely to be at any given time, except for the f orbitals, as no one really knows for sure what those look like yet.

What is nothing exactly?
Nothing is nothing yet it is something. Nothing is not colored yet it is colored. Nothing is everything yet it is nothing, too. You can not really describe nothing.

What do the colored ecstasy pills mean?
The colored x pills are more potent yet more dangerous then the non colored pills. Try a triple stack thizz pill, you might die but itll be fun.

Potassium 595mg equals how many potassium meq?
how many meq's is 595 mg of potassium gluconate in pill form? _____________ You seem to be asking how translate a dose of potassium chloride, which is often expressed as mEq's when prescribed as a drug, into an equivalent dose of potassium in supplemental potassium gluconate, which is generally expressed in mg. 595 mg of potassium gluconate contains about 99mg of elemental potassium. 189 mg of potassium chloride also contains about 99mg of elemental potassium. 189 mg of potassium chloride is about 2.54 mEq That said, the potassium in potassium gluconate is more easily absorbed by the body than is the potassium in potassium chloride, so seeking the equivalent elemental potassium dosage may not be what you want as it may produce different effects in the body. For example, my mother had been prescribed 20mEq of potassium chloride by her doctor, which contains 781.960 mg of elemental potassium. The large pills were hard for her to swallow. Instead i gave her about 1/4 teaspoon of powered potassium gluconate mixed in a glass of water, which contained only about 135 mg elemental potassium, about the same contained in 3.5 mEq of potassium chloride. That was less than a fifth the amount prescribed by her doctor, yet her potassium levels in her blood tests were just fine.
How long will the orbital between the Earth and Moon last?
This is a question that has not yet been answered by NASA nor is found on the internet.But it will depend on the space environment around us.
Why would a physician give a diabetic lasix yet stop rx for potassium which is supposed to be taken when on diuretic medication?
Yes, sometimes when you take a diuretic you need to take potassium to ensure the proper level. However, the doctor will probably do regular blood work to check the potassium levels. If you are taking 20mg of lasix you may not need the potassium. If you are concerned don't be afraid to ask your doctor. Thanks, JM
