- Enzymes can be regulated in a many different ways. Covalent modification is one way. Here, the functional groups are attached to or removed from the enzyme. A phosphate group is an example of a functional group that can be added to an enzyme. Depending on the enzyme, addition of a phosphate group can either increase or decrease an enzyme's activity. Evaluate the following names and identify the general name of an enzyme that functions to add phosphate groups to its substrate? A. isomerase B. phosphatase C. kinase D. ligasearrow_forwardWhich of the following statements about the Michaelis Menten constant (Km) is correct......A. can be determined by plotting the data v/[S] against 1/[S] B. A large Km indicates a low affinity between the enzyme and the substrate C. A large Km means that a large concentration of substrate is needed for the enzyme to work D. is a measure of the affinity of enzymes for proteins, minerals and vitamins E. Small Km means that a large concentration of substrate is needed for the enzyme to workarrow_forwardSelect all the true statements about sequential versus concerted models of allostery. a. In sequential allostery, binding of the substrate on one end of an enzyme causes a conformational change on the other end which propagates to another enzyme and enables easier binding of a second substrate to the second enzyme b. No conformational changes occur in either model c. In concerted allostery, the two forms of the enzyme exist in equilibrium because of a conformational change independent of substrate binding d. In concerted allostery, binding of the substrate to one of the forms is favorable (but not to the other) and binding of the second substrate is enhanced on the favorable formarrow_forward

- The concept of “induced fit” refers to the fact that: a. enzyme specificity is induced by enzyme-substrate binding. b. enzyme-substrate binding induces an increase in the reaction entropy, thereby catalyzing the reaction. c. enzyme-substrate binding induces movement along the reaction coordinate to the transition state. d. substrate binding may induce a conformational change in the enzyme, which then brings catalytic groups into proper orientation. e. when a substrate binds to an enzyme, the enzyme induces a loss of water (desolvation) from the substrate.arrow_forwardWhich of the following enzyme classes catalyze reactions in which two molecules become covalently linked to each other? A. Kinase B. Hydrolase C. Isomerase D. Ligasearrow_forwardWhich one of the following statements is true of enzyme catalysts? a. Their catalytic activity is independent of pH. b.

A. Allosteric enzymes are always multimeric. B. Regulatory sites (allosteric sites) on an allosteric enzyme are always different from the catalytic site. C. Allosteric enzymes always change the conformation of the active site in response to binding of an allosteric modulator. D. Suicide inactivators are examples of allosteric modulators.arrow_forwardEnzymes are catalytic proteins or RNA molecules that accelerate chemical reactions. Substrates are the molecules that are acted upon by enzymes and are converted into products through the binding of substrates to an enzyme’s active site. Figure 1 below shows a protein enzyme’s active site and four potential protein substrates. Table 1 indicates the different chemical properties at several locations in a hypothetical enzyme’s active site, and Table 2 indicates the different chemical properties at several locations in the potential substrates. Locations labeled “A” in the enzyme’s active site and on the substrate will attempt to interact, as will locations that are labeled “B” and “C. Based on Figure 1, explain whether the enzyme is more likely to bind with substrate 2 or substrate 4.arrow_forward
