PPT-Enzymes and Temperature

Lesson 3 Starter Think pair share Effect of temperature on enzymes Success Criteria Describe and explain the effect of temperature on enzyme activity Explain what happens to an enzyme when it denatures . Reactions. Most reactions take place in a number of steps which need to be carefully controlled if the cell is to function properly. Enzymes are the most important controllers of cellular reactions. Catalysts. Essential idea: Enzymes control the metabolism of the cell.. Above is just a small part of the IUBMB-. Sigma-Nicholson Metabolic Pathways Chart . aims to show all the metabolic pathways found in eukaryote cells. The chart in it's entirety shows how complex the chemicals reactions needed to support life in a single cell unit. This was mentioned earlier in 2.1, but in addition to the complexity now add to that . Are specific for . what they . catalyze . and do not permanently change during reactions. End in the word -. ase. Function of Enzymes. Enzymes work by lowering the activation energy (the amount of energy needed to start a reaction). . Identify the three factors that impact enzyme functionality. . Question:. . Identify five functions of proteins. . State the four macromolecules and the monomers of each.. Grab a Chrome . B. ook when finished.. 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 . Restriction enzymes. Polymerase enzyme. Strand-displacing polymerases. Helicase enzymes. Discovery and Obtainability:. Most enzymes are proteins discovered in cells.. But .

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. XI. Adjust the pH of the enzyme buffer at the temperature at which it will be used. Manycommon buffers are exceptionally sensitive to temperature. The pH of a solution containing the buffer Tris dec Today’s Objectives. Describe a general enzyme-catalyzed reaction. Discuss the relation of temperature and pH to rate of reaction in an enzyme-catalyzed reaction. Explain how chemical reactions are affected by enzymes. 1-. Describe . enzyme nomenclature. . 2-Explain the Classification of enzymes. 3-Study the. mechanizem action of enzymes. 4-illusterate factors affecting enzyme activity. . Enzyme nomenclature. Two Systems: . Objective: BIO.A.2.2.3: Compare and contrast the structure and function of carbohydrates, lipids, proteins, and nucleic acids in organisms. . Objective: To describe the function of . enzymes . inside living things.
