WebAllosteric enzymes are regulated by inhibitors that Select one: a. compete for an active site with the substrate. b. bind to the enzyme at a different site to the active site. c. break down the enzyme tertiary structure. d. stabilise subunits in an active form. In reality, most enzyme mechanisms involve a combination of several different types of catalysis. The role of glutathione(GSH) is to remove accumulated reactive oxygen species which may damage cells. During this process, its thiol side chain is oxidised and two glutathione molecules are connected by a disulphide bond to form a dimer(GSSG). In order to regenerate glutathione the disulphide bond has to be broken, In human cells, this is done by glutathione reductase(GR).

WebAllosteric enzyme s typically have multiple active sites and often display cooperativity, meaning that the binding of a substrate at one active site increases the ability of the other active sites to bind and process substrates. WebMay 18, 2024 · The active site of an enzyme has the exquisitely selective affinity for its substrate (s). This affinity is many times greater than those of inorganic catalysts for generic reactants. The result is that enzymes are more efficient, faster catalysts.
