What is the purpose of an enzyme? It is a protein molecule that is used as a biological catalyst in order to speed up a biochemical reaction. 2. What are the 4 general properties of an enzyme? a. High Reaction rate: speeds up the reaction by lowering the transition state. b. Specificity: enzymes only recognize specific substrates for its active and regulatory sites c. Mild reaction condition: can occur at biological temperatures, pressures, and pH d. Regulated: activity can be regulated to allow metabolic efficiency and flexibility. 3. Reaction Rate What is the main mechanism used by enzymes to increase the rate of reaction? Explain how the mechanism works. Enzymes preferentially bind to the transition state , which stabilizes it and lowers the energy of activation. This causes the increase in rate of reaction. Red line: uncatalyzed reaction. Blue line: catalyzed reactionThis study source was downloaded by 100000859819779 from CourseHero.com on 01-20-2023 10:32:52 GMT -06:00https://www.coursehero.com/file/12488945/Session-5-Enzyme-and-Enzyme-Class-Answers/Session 5 Enzymes and Enzyme Class 4. Regulation A. Enzyme binding sites: 1. Active Site: allows binding of substrate and catalysis of
