Which part of a liver cell is responsible for controlling the production of reductase?
The microsomes of liver cells contain an ATP-dependent protein kinase (‘reductase kinase’) that inactivates HMG-CoA reductase by phosphorylating it, and the cytosol contains a phosphoprotein phosphatase that activates the reductase by dephosphorylating it (Ingebritsen et al., 1978).
When Fertiliser goes into the river the concentration of oxygen dissolved in the water decreases?
