Some cool enzyme (CE) catalyzes the conversion of compound F to compound A. Which of the following must be true of CE? Choice 1 of 4: CE can facilitate conversion of compound A into compound F. Choice 2 of 4: CE binds more tightly to the substrate F than to the product A. Choice 3 of 4: CE decreases the energy of the transition state between compounds F and A. Choice 4 of 4: CE facilitates net conversion of F to A whenever F is present.
Catalysis through proximity and orientation effects involves: (select all that applies) Group of answer choices binding of acidic and/or basic groups in the binding site facilitating chemical reactions by binding substrates close to specific groups binding of substrate in specific, restrictive orientations depending on metal ions for catalysis
At the left is an energy diagram that shows the energy changes for the example of glucose (C6H1206) being converted to CO2 + H2O. One curve is the reaction with enzymes, while the other is without enzymes. For these reactions, the "X" indicates: Glucose + 60g a) b) free energy of glucose free energy of activation without enzymes free energy of CO2 + H2O free energy released free energy of activation with d) e) Progrem af reaction enzymes Frec energy, G
Which of the following statements regarding enzymes and transition states is true? stabilization of the transition state must be less than stabilization of ES for catalysis to occur binding of substrate to an enzyme often causes strain, thus promoting transition state formation the transition state conformation of an enzyme catalyzed reaction is identical to the conformation seen in the uncatalyzed transition state formation of the transition state always assures that the reaction will proceed to product none of the above are true
Which class of enzymes have sigmoid or S-shaped plots of the rate of a reaction, v, versus the substrate concentration, [S], instead of the hyperbolic curves of the Michaelis-Menten equation? transferases holoenzymes O hydrolases O allosteric enzymes O ribozymes
With a ∆G°´ of -16.7 kJ/mol, the reaction catalyzed by hexokinase is considered to be _____. at equilibrium substrate and product concentration dependent freely reversible metabolically irreversible none of the above
Many biosynthetic pathways are regulated by feedback control, where the product of a pathway turns off an enzyme that catalyzes an early step in the pathway. Usually, this control comes from an allosteric interaction. Of the types of reversible enzyme inhibition (Competitive inhibition, Noncompetitive inhibition, and Uncompetitive inhibition), what type is most likely to occur in a feedback control mechanism like this and why?
