What has to occur for an enzyme to catalyze a reaction? Select all correct.

A.	The enzyme and substrate cannot interact with each other
B.	The enzyme and substrate have to undergo a chemical with each other
C.	The enzyme and an inhibitor have to come into contact at the active site
D.	The enzyme needs to become denatured prior to contact
E.	The enzyme and substrate have to undergo temporary non-covalent interactions with each other
F.	The enzyme and substrate have to come into contact at the active site

Expert Solution

Ans) The correct options are "E and F"

Substrate binds to the active site of an enzyme to form Enzyme-substrate complex which is then converted into product. They may form hydrogen bonds,hydrophobic interactions or transient non-covalent interactions. Every enzyme has its optimum activity at particular pH,Temperature etc above or below which its activity decreases.Denatured enzymes cannot catalyze chemical reaction efficiently because with elevated temperature the bonds are disturbed and thus low reaction efficiency. Inhibitors can bind covalently,reversibly or irreversibly to change the conformation of the enzyme so that the enzyme cannot bind to the substrate and thus no chemical reaction is catalyzed when inhibitor is present.

(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. Reaction rate constants increase with increasing temperature. Solid catalysts increase reaction rates as their surface areas increase. The rate of a reaction is the same as the rate constant of the reaction. The slowest step in a reaction is called the rate-determining step. Reaction rates increase with increasing temperature. The rate of...

Select all of the correct statements about reaction quotients and equilibrium constants from the choices below. A reaction quotient equals the equilibrium constant at equilibrium. K changes as temperature changes, but is independent of concentrations. If Q = K the reaction is already at equilibrium. A reaction quotient is the same as an equilibrium constant. The richer a reaction mixture is in product the higher its Q value is. As a reaction approaches equilibrium its Q value rises and its...
