The concerted model (MWC) is based on several premises. What are they? O Allosteric enzymes follow a hybrid rule. Active sites for a single enzyme can be both Tor R. O Allosteric enzymes follow a symmetry rule: All active sites for a single enzyme are in the same state (either Tor R). O Allosteric enzymes have a single active site. Allosteric enzymes exist in 3 conformations. T, R, and S. Allosteric enzymes exist in two conformations. T and R. O Allosteric enzymes have multiple active sites. Allosteric enzymes are information sensors because they exist in two conformations: T and R. Binding of substrates or regulatory molecules stabilize either the T form or the R form. Which of the following is true about T and R? Choose four correct statements. OR=repressed. This form of the enzyme is catalytically less active. O T& Rexist in equilibrium. R is more stable than T. OT& Rexist in equilibrium. T is more stable than R. Substrates have a higher affinity for T O T = tight. This form of the enzyme is catalytically more active. OR=relaxed. This form of the enzyme is catalytically more active. Substrates have a higher affinity for R. O T = tense. This form of the enzyme is catalytically less active.
