A complex signaling pathway in yeast allows the cells to accumulate high concentrations of glycer...
A complex signaling pathway in yeast allows the cells to accumulate high concentrations of glycerol if they are exposed to high extracellular concentration of salt or glucose. The increased osmolarity of the extracellular medium activates Ras, which in turn activates adenylate cyclase. A second pathway, the HOG (high osmolarity glycerol) pathway activates the MAP kinase pathway. The target protein is the enzyme PFK2, which is activated by phosphorylation. (PFK2 produces an allosteric regulator that activates glycolysis, which ultimately produces glycerol.)...

under the derms of the skin. Tus II S UV y Puomu solution A has a lower solute concentration (or lower osmolality) than solution B. The prefix hyper means above or greater. For example, a hyperactive kid has a greater activity level than a normal kid. In the above example, B has a greater solute concentration than A, thus B is hyperosmotic to A. The prefix iso means the same or equal. Two solutions that are isosmotic to each other...
