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.

Enzymes are proteins that speed up the rate of chemical reactions.Describe how a change of one of the bases in the gene for an enzyme could affect the functioning of that enzyme.

How do enzymes affect the rate of reactions?Enzymes decrease the rate of reaction via the binding of substrates to the enzyme active site.Enzymes increase the rate of reaction without being used up. This is achieved by the binding of substrate to the enzyme active site, where the reaction is catalysed.Enzymes decrease the rate of reaction via the binding of substrates to the enzyme active sites. Enzymes act as reactants.Enzymes increase the rate of reaction via the binding of substrates to the enzyme active sites. Enzymes act as reactants.I DON'T KNOWSUBMIT ANSWER

How do enzymes speed up the rate at which a biological reaction occurs?Group of answer choicesBy increasing the energy of the reactant molecules.By increasing the total amount of energy released by the reaction.By decreasing the amount of energy needed to proceed through the reaction.By increasing the energy of the product molecules.By making the reaction release energy rather than requiring energy.

Which of the following correctly describes how enzymes lower the activation energy of a biochemical reaction?Question 8Answera.Enzymes increase the temperature of the reaction, providing more energy to the reactants.b.Enzymes stabilize the transition state, reducing the energy required to reach it.c.Enzymes alter the equilibrium constant of the reaction, favoring product formation.d.Enzymes are consumed in the reaction and must be continually replaced.

Which of the following statements are true of enzymes?SELECT ALL THAT APPLYEnzymes are permanently changed in a reaction.Enzymes are involved in catabolism but not in anabolism.Enzymes produce specific products from specific substrates.Enzymes provide a route from reactants to products that has a lower activation energy.Enzymes can be regulated to control cellular metabolism.All enzymes require cofactors for activity.
