Study all notes. Concentrate on studying enzymes notes. Divide your desk into four columns. Label each column with the four organic macromolecules. Draw a picture of each macromolecule. List the elements that make up each macromolecule Erase all info in the columns and leave the titles. Write ALL the functions of each macromolecule in the respective column. Give at least two examples of each. Erase your entire desk. What is the difference between an organic and an inorganic compound? Give an example of each. What is the difference between a monomer and a polymer? Describe and illustrate how a monomer becomes a polymer. Describe how a polymer becomes a monomer. Differentiate between reactants and products. Describe the general chemical equation X+Y XY in words What type of macromolecule is an enzyme? What type of reactions are more likely to occur spontaneously? What is the purpose of a biological catalyst? Identify all parts of this graph True or False: 1. enzymes are not changed by the reaction they speed up 2. enzymes cannot be recycled and reused many times. 3. Enzymes are specific to the reactions that they catalyze. 4. One enzyme can catalyze reactions at a variety of pH and temperature levels. 5. The substrate of a reaction is the same as the products. Describe to concept of induced fit. How does it differ from the lock and key model of enzymes? Draw and label all parts of the enzyme substrate complex. Include: Enzyme Substrate Active site Products DO NOT ERASE Add a non competitive inhibitor to your picture. Describe how it works. Add a competitive inhibitor to your diagram. Describe how it works. Add a coenzyme to your picture. Describe how it works. What is the optimal pH for pepsin? Trypsin? The intestines are basic and the stomach is acidic. Which enzyme works best in each environment. What happens to the pepsin as it moves into the intestines? ____________ - breaks down starch ____________ – breaks down H2O2 _____________ – joins DNA nucleotides to build DNA _____________ – Unwinds the DNA molecule __________ – break apart fats ___________ – breaks apart lactose – milk sugar ___________- breaks apart protein molecules
