Enzymes using BioMan Biology or Enzymatic App on iPad Go to the website Bioman Biology: The Fun Place to Learn Biology! and click on Life Chemistry and then Enzymatic or if using the iPad, click on the Enzymatic app 1. Use the information that you learn from the What are Enzymes option to answer the following: a. What are enzymes? Proteins that speed up or catalyze chemical reactions, extremely important as all organisms rely on chemical reactions for survival b. What is metabolism? The chemical reactions referred to in the previous answer are what make up metabolism c. What are two types of reactions that occur in metabolism? Hydrolysis and dehydration synthesis (condensation) 2. Use the option Specificity to help you answer the following questions: a. What is specificity? The shape of an enzyme active site that will only catalyze a reaction with a specific substrate b. What is an active site? A place on an enzyme that binds to a substrate c. What are substrates? A chemical reactant to which an enzyme binds with d. What are products? The result of chemical reactions

3. Use the options Experiments and summarize the effects of the following on enzyme functions (you may want to draw graphs) a. Temperature The warmer the temperature gets, the faster the enzymes move until it reaches optimal temperature. The reaction rate slows down drastically when the temperature is too high due to the enzyme losing shape and no longer effectively catalyzing the reaction. b. pH It stays between the optimal range but denatures if it exceeds the temperature or drops too low c. Substrate Concentration Once the maximum reaction rate for the enzyme is reached, the reaction rate levels off. There is more enzyme activity at higher substrate concentrations due to more collisions between enzyme and substrate until a maximum reaction rate is reached. The graph for substrate concentration shows the rate leveling off when substrate concentration is high, instead of declining when not in the optimal range. Changes in the substrate concentration don’t cause the enzyme to denature, but changes in temperature and the pH may cause it to 4.
