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:. 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. immobilised enzyme enzyme 21. An enzyme specifically through a this respect, lipoamide dehydrogenase particularly useful enzyme comprises two polypeptide chains each binding binding and containing 10 Inhibition. C483 Spring 2013. Questions. 1. . An inhibitor binds to a site other than the active site of the enzyme. Which statement below correlates with this observation? . A. ) It must be a competitive inhibitor. . 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.
