How will each of the following changes in conditions alter the rate of an enzyme-catalyzed reaction? Select the single best answer for each part.Part 1 of 2Increasing the temperature from 37°C to 100°CNo effect on the rate of reactionIncreases the rate of reactionDecreases the rate of reaction until the reaction stops

What is the rate of Enzyme reaction and what are the factors that affect it.

. Under what conditions will the rate of a chemical reaction always decrease?*the concentration of the reactants decreases, and the temperature decreasesthe concentration of the reactants decreases, and the temperature increasesthe concentration of the reactants increases, and the temperature increasesthe concentration of the reactants increases, and the temperature decreases

All of the following are true of enzyme-catalyzed reactions EXCEPT:A.the presence or absence of a post-translational modification may alter the activation energy Ea of the reaction.B.the enzyme does not affect the net reaction rate if the ratio of products to reactants equals Keq for the reaction.C.substrates can covalently modify the enzyme to cause a permanent decrease in the enzyme's turnover number kcat.D.the saturation of enzyme active sites by substrate molecules limits the maximum reaction velocity Vmax.Submit

Enzymes are catalysts that affect biological reactions. How do enzymes change the rates of reactions in the body?A.Enzymes decrease reaction rates by decreasing the energy of the products.B.Enzymes decrease reaction rates by lowering the activation energy.C.Enzymes increase reaction rates by lowering the activation energy.D.Enzymes increase reaction rates by increasing the energy of the reactants.
