- What effect does an enzyme have on the required activation energy of a reaction?arrow_forwardDiscuss the following statement: “enzymes and heat are alike in that both can speed up reactions that—although thermodynamically feasible—do not occur at an appreciable rate because they require a high activation energy. diseases that seem to benefit from the careful application of heat—in the form of hot chicken soup, for example—are therefore likely to be due to the insufficient function of an enzyme.”arrow_forwardWhich of the following is not a mechanism that enzymes use to lower the activation energy of a reaction?arrow_forward
- Decarboxylases can catalyze which type of reaction?arrow_forwardThe figure below represents a reaction in the presence and absence of an enzyme catalyst. What can you conclude about this reaction? energy activation energy activation energy 1 uncatalysed reaction catalysed reaction A) It is endergonic in the absence of the enzyme. B) It will proceed more quickly in the presence of the enzyme. C) Once the reaction has reached equilibrium, there will be more product in the enzyme-catalyzed reaction. D) It has a negative AG. OE) Both B and D are truearrow_forwardWhich enzyme catalyzes the reaction?arrow_forward
- Describe the reactants and products of the following enzyme catalyzed reaction. Names of molecules are sufficient.arrow_forwarda) Describe a specific chemical reaction that occurs within the human body and state the name of the enzyme involved, the substrate(s) of the reaction, and the specific product(s) formed. b) Enzymes are not used up in chemical reactions. So, what exactly does an enzyme do? In your answer you should refer to activation energy. c) Explain what is meant by the induced fit action of an enzyme, referring to the role of the active site, and to the activation energy of an enzyme-catalysed reaction.arrow_forwardEnzymes are biological catalysts that fulfill the following general reaction mechanism: E+S [ES] [EP] E + P Where E is enzyme, S is substrate, and P is product. Briefly describe how an enzyme is able to speed of the rate of a reaction:arrow_forward
- Describe enzyme inhibition.arrow_forwardEnzymes use several types of catalytic mechanisms. Differentiate between acid-base catalysis, covalent catalysis, and metal ion catalysis.
