Monday, September 9, 2013 ( 5 th & 7 th ) What type of macromolecules is an enzyme? WARM UP
ENZYMES A TYPE OF PROTEIN
OBJECTIVES 1. Identify the role of enzymes 2. Describe the components of an energy hill diagram
ROLE OF ENZYMES Characteristics 1) are proteins 2) Are catalyst 3) End in –ASE (Ex: Amylase in saliva) Catalyst = speeds up the rate of a chemical reaction
ACTIVE SITE Substrate = material on which enzyme acts Active Site = site of chemical reaction between (btw) substrate & enzyme
LOCK AND KEY Enzymes & substrates Lock & Key relationship Enzymes will fit a SPECIFIC substrate
ACTIVATION ENERGY Activation Energy = energy needed to get a reaction started
ENERGY HILL DIAGRAM (enzyme)
LABEL: REACTION W/ AN ENZYME Substrate Enzyme (does NOT change) Products Active Site Lock & Key Fit
ENZYMES AS ROBOTS Enzymes perform the SAME reaction over and over again The enzyme is NEVER altered! Only the substrate.
INHIBITORS Inhibitor = molecule that binds to enzymes & decreases their activity Competitive Inhibitor = binds to active site of enzyme & prevents substrate binding Ex. Chemotherapy
ENZYMES IN YOUR BODY Enzymes found in saliva: 1.Amyl ase - help break down carbs 2.Prote ase - help break down protein 3. Lip ase - help break down fats
ENZYMES IN PRODUCTS Laundry Detergent- (Tide, Arm & Hammer, Oxy Clean) contains protease, amaylase and mannanase Frizz Ease- contains dismutase; converts superoxide and protons.
REMINDER: SUMMARY Draw horizontal line at end of notes Write “Summary” Write 3-5 sentences about specific things you learned about enzymes Use COMPLETE sentences
CREATE AN ENZYME 1.Create an enzyme that would help you in your life. (Example: helps you finish a chore in 1 minute) 2.Name the enzyme (remember end in –ASE) 3.Draw a picture of the enzyme. Use at least 3 colors. 4.Write 2 complete sentences explaining how the enzyme will help you out. ***Worth 4 stamps…remember you can earn a 5 th stamp for extra credit if you create a WOW assignment***
ENZYME READING ASSESSMENT Instructions: ***Do NOT write on the handout*** 1. The provided reading is divided into 4 sections. Read each one. 2. Summarize each section using a 7-9 word complete sentence. (you should have 4 short summaries) 3. After you complete the 4 sections, summarize the entire passage using words. (5 summaries total) **THIS DOES NOT TAKE ANY TALKING**
Monday, September 9, What suffix do enzymes end in? (Hint: 3 letters) 2.In a chemical reaction which component is altered? (Hint: labeled diagram below) WARM UP
WARM UP Tuesday, September 10, 2013 Draw an energy hill diagram. Label the reactants, products, activation energy, and enzyme line. Use your notes or the provided textbook.
ENZYME LAB 1)Title your page (spare sheet of paper) Enzyme Lab 2)Paste the table on your sheet. Fill in the table as your complete each task. 3)Answer the questions on your lab sheet under the table using complete sentences on your spare sheet of paper.
WARM UP Wednesday, September 11, 2013 What is attaching to the enzyme in the following picture?
WARM UP Thursday, September 12, 2013 What biomolecule is represented by the following picture?
WARM UP Friday, September 13, 2013 What is the most important thing YOU personally learned in the biomolecules unit?
