C483 Spring 2013. Questions. 1. Which . statement is false about allosteric regulation? . A) It is usually the mode of regulation for the last step in reaction pathways since this step produces the final product. . Lecture 3. Objective. To understand . Specificity of enzymes. Specificity means:. Ability of an enzyme to . catalyse. a specific reaction and NO others. The active site. The . active site, . is. . 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. Pratt & . Cornely. . Ch. 7. Other Factors. Other factors affect enzyme activity. Temperature. pH . pH Optimum. Determined by structural stability. Compartmentalization. Determined by active site residues. Mechanisms. C483 Spring 2013. Questions. 1. . Replacement of the amino acid ________ at or near an active site of an enzyme is more likely to change enzyme activity than the replacement of ________ at or near the active site..

Why study enzyme kinetics?. Helps us understand mechanism of enzyme (how it works). Investigation of mutations in metabolic pathways. Protocol 10.1 through 10.3. Objective. : To cut phage genome into multiple fragments based on DNA sequence. General Introduction on Restriction Enzymes. Are also known as restriction endonucleases. Are naturally occurring enzymes used by bacteria for defensive purposes against extraneous DNA molecules. Biology. Do not appreciate the awesomeness of enzymes!!!!. How do enzymes work?. Lock and key theory. Enzymes have a specific 3D structure. They exactly match the shape of a molecule of substrate. How do enzymes work?. Objectives. To monitor the progress of an enzyme catalyzed reaction (Acid phosphatase).. To determine the initial rate of the reaction (. V. i. ).. Important terms and points:. Enzyme kinetics. The central approach for studying the mechanism of an enzyme-catalyzed reaction is to study enzyme kinetics. . Introduction:. All . enzyme assays measure either the. consumption of substrate or production of product over time. . Different enzymes require different estimation methods . dependingon. the type of . Topic 2: . Enzyme. . Kinetics. What is an Enzyme?.  . Enzymes: .  are biological molecules (proteins) that act as . catalysts*.  and help complex reactions . take place. Basically, they . break a protein down into its amino . Therapy of enzyme defects: general considerations. How many organs are affected by the enzyme defect: One organ, a few, or all organs?. How severe is the defect?. Can the defect be adequately controlled by conventional treatment?.
