- Aquaporins are special channels made of protein and deposited into the cell membrane. Similar to a tunnel, they let molecules travel through them, entering or exiting the cell. Aquaporins are highly specific and let only water and nothing else pass through. 'Aquaporin' is therefore a great name for this protein, since 'aqua' means water and 'porin' means tunnel. Most cell membranes have many aquaporins, so the cell can react quickly to consistently maintain proper balance within the cell. Special Functions

What are aquaporins? Aquaporins are a class of integral membrane proteins or more commonly referred to as a class of major intrinsic proteins (MIP) that form pores in the membrane of biological cells. Genetic defects involving aquaporin genes have been associated with several human diseases.

Aquaporin Water Channels in Kidney AQP2, the Vasopressin-Regulated Water Channel. Water permeability of renal collecting ducts is regulated by vasopressin. The failure to demonstrate AQP1 in collecting ducts by immunohistochemistry (10) led to the prediction that other members of the aquaporin family must exist at this site (18).

auxin Auxins (plural of auxin) are a class of plant hormones (or plant growth substances) with some morphogen-like characteristics. Auxins have a cardinal role in coordination of many growth and behavioral processes in the plant's life cycle and are essential for plant body development. Auxins and their role in plant growth were first described by the Dutch scientist Frits Warmolt Went.

Aquaculture Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants.he aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.

Aquaporin Crystallographic structure of aquaporin 1 (AQP1) PDB 1j4n. Aquaporins also called water channels, are integral membrane proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cell than by diffusing through the phospholipid bilayer. The 2003 Nobel Prize in Chemistry was awarded joint

- Increase in permeability of the cells of the collecting tubule to water is due to an increase in the production of antidiuretic hormone (ADH).   Aquaporins are constant com … ponents of the tubule cells membranes. Unless ADH is present, aquaporins are virtually absent in the luminal membranes of the collecting duct.

Cephalosporins: Four Generations of Beta-Lactam Antibiotics Four Generation of Cephalosporins. Cephalosporins are β-lactam antibiotics, which are grouped into four generations according to their antibiotic spectrum of activity. The first generation has mainly gram-positive activity. The second and third generation has more gram-negative activity with mostly decreased activity against gram-positive bacteria.

Auxin Auxin (Science: plant biology) a group of plant growth substances (often called phytohormones or plant hormones), the most common example being indole Acetic Acid (IAA), responsible for raising the ph around cells, making the cell wall less rigid and allowing elongation. auxins include indoleacetic acid, phenylacetic acid, and 4-chloro-indoleacetic acid. Commercially, auxins are used to promote root growth, to promote uniform flowering, and to set fruit and prevent premature fruit drop. Synthetic auxins such as 2, 4-D and 2, 4, 5-T have been used as herbicides, broad-leaved weeds like dandelions are much more susceptible to auxins than narrow-leaved plants like grass and cereal crops.
