Chapter 2: Section 2.5. 1. Objectives. SWBAT explain the effect of a catalyst on activation energy. . SWBAT describe how enzymes regulate chemical reactions. . and maintain homeostasis.. 2. Starter: How can this be possible. Enzymes speed up chemical reactions.. Everything that happens in a cell. Growth. Reproduction. Interaction with the environment. Response to stimuli. Is the result of a chemical reaction.. A chemical reaction is a change in the arrangement. IMPORTANCE. OF ENZYMES. Enzymes are biological catalysts that:. . I. ncrease. . reaction rates . by lowering the amount of energy needed for the reaction to occur. 100-1000x . faster. !!!. Activation Energy. 1. What are enzymes?. Each enzyme has only one specific reaction it can perform. . 2. How many different reactions can a single enzyme perform?. Yes, the same enzyme molecule can be used over and over. protein. !. Enzymes are . Biological . catalysts . that . increase. . the rate of metabolic reactions.. Since enzymes speed up chemical reaction rates, what are they called?. Catalyst- . A substance . Part 1. . Chapter 3. Learning outcomes. You should be able to:. explain how enzymes work. describe and explain the factors that affect. enzyme activity. use V. max. and K. m. to compare the affinity of different enzymes for their substrates. Enzyme & Substrate. An enzyme is a globular protein which acts as a biological catalyst by speeding up the rate of chemical reactions. . Enzymes are . NOT. changed or consumed by the reactions they catalyze and thus can be reused. . To the penny placed on your desk.. Observe the penny but don’t touch it. What happens?. Explain why. 2. Give the penny a . little . push. What happened?. Why did the penny move the second time and not the first time?. Factors affecting enzymatic reactions. Enzymes specificity. Enzymes kinetics and mechanism of action. Control of metabolic pathways. Enzymes inhibition. Enzymes in clinical diagnosis. Enzymes and genetic diseases. Presented . by. Ms. . P. . . H. . Giri.
