Lab Presentation By May Nam T Por Parn Mook Mix 109 Objective To study how pH temperature ionic conditions substrate concentration affects enzyme activity Something you should know before . Watch the PowerPoint presentation and copy the notes.. When finished, assemble in a lab group of 2 students and begin planning your experiment.. A rough overview of your experiment is due at the end of class that includes:. Learning Objectives. Learn how the rate of an enzyme controlled reaction is measured.. Learn how temperature affects the rate of an enzyme controlled reaction.. Learn how pH affects the rate of an enzyme controlled reaction.. 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. Lecturer Dr. . Kamal. E. M. . Elkahlout. Assistant Prof. of . Biotechnology. 1. CHAPTER 1. Fundamentals of Enzymes. 2. Fundamentals of enzymes. Why enzymes?. Enzyme nomenclature. Enzyme . units. Sources of . Some reactions have enzymes. What might be an advantage to having enzymes in chemical reactions? Any disadvantages?. Can you name any enzymes?. Bellringer-3/9/15. Enzymes. Most enzymes are proteins. Act as a catalyst to speed up a chemical reaction by helping molecules react with each other faster. 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 . 322 BCH. Exp. (8). In this experiment, we will continue to study . acid phosphatase . kinetics.. Objectives. To . study the effect of inhibitors on the rate of an enzymatic reaction.. To . determine the type of inhibition of acid phosphatase by inorganic phosphate and sodium fluoride. . 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?. Objectives. -Understand how Restriction Enzymes digest DNA.. -Know how to construct a . pAMP. . (plasmid) or gel.. -Given the size of fragments, gel, know how to construct a restriction map.. -Given a restriction map know how to construct a gel.. Bio-Rad Biotechnology . Explorer™ Biofuel Enzyme Kit. Instructors - Bio-Rad Curriculum and Training Specialists. Sherri Andrews, Ph.D. ., Eastern US. sherri_andrews@bio-rad.com. Damon . Tighe. , . 1 In this exercise we will look at the catalytic behavior of enzymes. You will use Excel to answer the questions in the exercise section. At the end of this session, you must hand in answers to all -. The SSERC Team. Effect of competitive and non. –. competitive inhibitors on . . ‑galactosidase. Paul Beaumont / Kate Andrews /. Margaret Louis. b. -galactosidase. b. -galactosidase. Competitive inhibition. A. . Activation Energy:. 1.. . All the reactions that proceed from initial substrates (initial state) to products (final state) consume energy. This is called free energy of the reaction.. 2.. However the substrates do not become products directly, but must be energized (absorb energy) to reach an activated or transition state. This energy is called activation energy.. 1. Enzyme concentration. 2. Temperature. 3. Hydrogen ion concentration or pH. 4. Substrate concentration. 5. Inhibitors. 6. Product concentration. 7. Activators. 8. Physical agents. Factor affecting enzyme kinetics.
