CLC proteins can either be ion channels or anion-proton exchangers, so CLC-1 and CLC-2 are membrane chloride channels, while CLC-3 through CLC-7 are chloride-hydrogen exchangers. [48] CLC-4 is a member of the CLC family that is prominent in the brain, but is also located in the liver, kidneys, heart, skeletal muscle, and intestine.
[4] An example of an antiporter mediated transport protein is the sodium-calcium antiporter, a transport protein involved in keeping the cytoplasmic concentration of calcium ions in the cells, low. This transport protein is an antiporter system because it transports three sodium ions across the plasma membrane in exchange for a calcium ion ...
In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement.

Biorientation is the phenomenon whereby microtubules emanating from different microtubule organizing centres (MTOCs) attach to kinetochores of sister chromatids.This results in the sister chromatids moving to opposite poles of the cell during cell division, and thus results in both daughter cells having the same genetic information.
