What form of cellular transportation helps human cells maintain their sodium and potassium concentration?
The sodium/potassium pump, the sodium leak channel and the potassium leak channel.
Which channel is mainly responsible for the resting potential of a neuron?
Potassium leak channel
What is the solubility of potassium in water?
Potassium is soluble in water but not in organic solvents.
Sodium and potassium ions both have a positive charge but potassium is larger and there is a protein channel that allows potassium ions through but blocks sodium ions and how is this possible?
These membranes have several types of selective ion channels. Some are nongates and always open, but for the potassium channel is gated, and only opens for the chemical potassium after specific conformational changes.
What substances are formed when potassium oxide dissolves in water?
When potassium oxide is dissolved in water it forms potassium hydroxide.
What is the chemical reaction of potassium oxide with water?
Potassium oxide(K2O) + water(H2O) --> potassium hydroxide(2KOH)
What type of channel is responsible for the action potential?
sodium potassium and calcium
Is potassium metal preserved under water?
No. Potassium will react violently on contact with water. Potassium is stored under oil to protect it from air and water.
Word equation for the reaction between potassium and water?
Potassium plus Water gives Potassium Hydroxide plus Hydrogen
What type of channel does sodium and potassium use to diffuse across the plasma membrane of all cells?
voltage type of channel
Chemical reaction for potassium nitride?
It reacts with water to produce toxic Ammonia
What happens when potassium react to water?
When potassium reacts with water the potassium burns a bright purple light, a gas is given off with a hissing noise and the potassium rockets around the surface of the water because it floats.
