Osmotic pressure is the basis of filtering ("reverse osmosis"), a process commonly used in water purification. The water to be purified is placed in a chamber and put under an amount of pressure greater than the osmotic pressure exerted by the water and the solutes dissolved in it.
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Activating transcription factor, ATF, is a group of bZIP transcription factors, which act as homodimers or heterodimers with a range of other bZIP factors. [1] First, they have been described as members of the CREB/ATF family, [ 2 ] whereas it turned out later that some of them might be more similar to AP-1 -like factors such as c-Jun or c-Fos ...
This process is related to osmosis, the movement of water across a selective membrane, which is why it is called "chemiosmosis". ATP synthase is the enzyme that makes ATP by chemiosmosis. It allows protons to pass through the membrane and uses the free energy difference to convert phosphorylate adenosine diphosphate (ADP) into ATP. The ATP ...

As four of these monomers come together to form the aquaporin protein, it is known as a homotetramer, meaning it is made up of four identical subunits. [ 15 ] [ 16 ] All aquaporins are tetrameric membrane integral proteins, and the water passes through each individual monomer channel rather than between all of the four channels.
The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...
ATF Form 4473, October 2016 revision. A Firearms Transaction Record, or ATF Form 4473, is a seven-page form prescribed by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) required in the United States of America to be completed when a person proposes to purchase a firearm from a Federal Firearms License (FFL) holder, such as a gun dealer.
