Membrane Potential - Physical Basis - Ion Pumps
... Ion pumps are integral membrane proteins that carry out active transport, i.e ... use cellular energy (ATP) to "pump" the ions against their concentration gradient ... Such ion pumps take in ions from one side of the membrane (decreasing its concentration there) and release them on the other side (increasing its concentration ...

Chemically Strengthened Glass
... Glass is submersed in a bath containing a potassium salt (typically potassium nitrate) at 300°C ... This causes sodium ions in the glass surface to be replaced by potassium ions from the bath solution ... These potassium ions are larger than the sodium ions and therefore wedge into the gaps left by the smaller sodium ions when they migrate to the potassium ...

Transmembrane Channels
... Ion channels are a type of transmembrane channel responsible for the passive transport of positively charged ions (sodium, potassium, calcium, hydrogen and magnesium) and negatively charged ions (chloride ... One of the best studied ion channels is the potassium ion channel ... The potassium ion channel can allow rapid movement of potassium ions while being selective against sodium ...
