· Loed 70km north of Marrakesh, Benguérir is the newest of Morocco's four phosphate mining centres, having started production in 1979–80. Operated by Office Chérifien des Phosphates (OCP), the opencast mine works 24h/d in three shifts and is managed together with the Youssoufia mining and treatment centre.

Pentose phosphate pathway (article) | Khan Academy

The pentose phosphate pathway can use any available molecules of glucose6phosphate, whether they are produced by glycolysis or other methods. Cellular respiration overview. Now, we are ready to enter the first of two phases of the pentose phosphate pathway: 1) .

Regulation of cell proliferation and cell density by the ...

· The inorganic phosphate (Pi) transporter, PiT1 (SLC20A1), is ubiquitously expressed in mammalian cells. It has previously been shown that downregulation of PiT1 severely impaired the proliferation of two transformed human cells lines, HepG2 and HeLa, and the tumorigenicity of HeLa cells in nude mice. Moreover, PiT1 knockout mice do not survive past and from, the embryos .

The sulfate permease of B. subtilis, CysP, is of 354 residues with 11 putative TMSs (Mansilla and de Mendoza, 2000). Phylogenetic grouping of the phosphate transport proteins generally correlates with organismal phylogeny. Thus the fungal, plant, animal and archaeal proteins each cluster separately (Saier et al., 1999).

Duurzaam vervoer: klimaatbewust op weg | Milieu Centraal

Duurzaam vervoer in het kort. Hoe je reist, heeft veel invloed op je klimaatimpact. Pak je bijvoorbeeld elke dag de fiets in plaats van de auto naar je werk, dan bespaar je veel CO2uitstoot. Met een elektrische fiets wordt het ook aantrekkelijker om op de fiets te stappen als je grotere afstanden af moet leggen.. Vliegen naar Thailand, treinen door Europa of met de auto naar Frankrijk?

Phosphorus Cycle

Mackey, A. Paytan, in Encyclopedia of Microbiology (Third Edition), 2009 Phosphorus Sources, Sinks, and Transport Pathways. The phosphorus cycle encompasses numerous living and nonliving environmental reservoirs and various transport pathways. In tracing the movement of phosphorus in the environment, the interplay between physical and biological processes becomes apparent.

Renal Control of Calcium, Phosphate, and Magnesium Homeostasis

· After absorption, phosphorus is transported across cell membranes as phosphate (31 mg/l elemental phosphorus=1 mmol/l phosphate). Phosphate in the plasma or extracellular fluid undergoes one of three fates: transport into cells, deposition in bone or soft tissue, or elimination predominantly by the kidneys.

a) Specimens from humans

WHO recommends two different transport media for use when taking samples from animals. Of these the transport medium based on tissue culture medium 199 (A) is widely used for collection and transport of clinical specimens from all species. A second medium, the glycerolbased medium

Phosphate transport in Arabidopsis: Pht1;1 and Pht1;4 play ...

Of the mineral nutrients essential for plant growth, phosphorus plays the widest diversity of roles and a lack of phosphorus has profound effects on cellular metabolism. At least eight members of the Arabidopsis Pht1 phosphate (Pi) transporter family are expressed in roots and Pht1;1 and Pht1;4 show .

Phosphorus Cycle

Phosphorus assimilation is a microbially mediated process, which is discussed in the section titled 'Transitory immobilization'. Phosphorus is transported within the environment through various mass transfer pathways. For example, rivers are important in the phosphorus cycle as both reservoirs and transport pathways.
