Question

Esmes can be conjugated with noeprotein gosents that carry out accivicies for which amino acid R A. are often referred to as B. can be organic and are then called D. can be metalloenaymes B, A,Band C %. Which property below is not a characteristic of A. They are roquired only in large amounts B. They can be altered reversibly during a reaction C. They function at optimal temperatures and pHs D. They are used repeatodly E. They do not determine whether a reaction is exergonic or endergonie 57. Enzymes work by A, raising the activation energy ofa reaction and thus spoeding up the reaction B. lowering the activation energy of a reaction and hus speeding up the reaction C. raising the AG (i.e the change in free energy) ofa reaction and thes speeding up the reaction D. neutralizing the AG ofa reaction and thus speeding up the reaction changing the free energy of the products and speeding up the reaction E 58. What kind of interaction is not involved in the binding of a substrate to a normally functioning enryme? A. H bonds B. A transient covalent bond C lonic bonds D. A permanent covalent bond E Hydrophobic interactions 9 What kind of inhibitor binds very tightly to an enzyme often forming a covalent bond with an amino acid in the active site? A. Irreversible B. Reversible D. A and C E. A and B 60. A competitive inhibitor regulatory site A. competes with the substrate for access to the B. competes with the substrate for access to the active site. C. typically resembles the substrate. D. must differ from the substrate in a way that prevents its conversion to a product B. C and D E.
