Enzyme PreLab Questions1.) What are biological catalysts and are they necessary for biochemical reactions to occur?
2.) Differentiate between anabolic and catabolic reactions in terms of both energy and products. 3.) Allosteric binding sites are locations on an enzyme that are situated away from the active site. How might chemical bonding at an allosteric site affect the performance of an enzyme? 4.) What environmental factors affect enzyme performance? 5.) Describe the 4 levels of protein structure. 6.) What is the importance of disulfide bridges in proteins? 7.) How does changing temperature, pH, and salt concentrations affect the performance of enzymes? 8.) Describe the enzyme-substrate reaction that will be performed in this lab. 9.) Defend or refute the following statement: Catalase enzymes in all plants and animals are identical in structure and function. 10.) Use what knowledge you already have to relate mutations in DNA to enzyme performance. |
