Set up page 12 for Cornell Notes Happy Thursday Bio-ninjas! Please follow the instructions in BOTH sections below. Journals: Table of Contents: Right Page 12 Enzymes Left Page 11 Enzyme Cutout Set up page 12 for Cornell Notes EQ: What is the function of an enzyme? Foldable Instructions: On the FRONT of the Protein door, color code the elements. C=green, O=blue, H=red, N=pink Also on the FRONT add important info from notes: Has an R-group, Enzymes, Shape determines function, “Peptide” Fill out the information on the inside flap. On the nutrition label to the right of the function flap, Highlight the Proteins in Pink

Card sort… You should be able to have better luck identifying Carbohydrates, Lipids and Proteins You have 2 minutes to find all the carbs and lipids….GO!

Homework tonight Page 10 left: Comic strip/Children’s story Carb, Lipid and Protein/Enzyme are your characters Dialogue must be about structure and function. Annotate Notes Biomolecule Handout

What is a Catalyst? (left side) Enzymes Notes: Before we can go any further we must first answer this question… What is a Catalyst? (left side) Some chemical reactions that make life possible are too slow to make them practical for living tissue. Catalyst: substance that increases the rate of chemical reactions by LOWERING the activation energy.

Common Catalyst Examples… Not much of a morning person… Match Maker…

Partner Activity: Explain what is happening in the graph

Enzymes lower the activation energy required to start a chemical reaction.

It takes less energy to get started, so the reaction happens faster!

Enzymes are special proteins that act as biological catalysts Enzymes are special proteins that act as biological catalysts. They speed up chemical reactions that take place in the cells of living things. Without them most of the bodily functions you take for granted could not happen.

II. How do enzymes work? Substrate: The substance the enzyme acts upon. Enzymes Are very specific, only act on one substrate.. Enzymes either break down the substrate or synthesize substrates into materials that cells need. Enzymes are reuseable. *Can perform the reaction numerous times without itself undergoing any permanent chemical change.

3. Enzymes usually end “–ase” and are named after what they do. lactase breaks down lactose (milk sugars) protease breaks down proteins found in meats, nuts, eggs, and cheese peptidase breaks down small peptide proteins to amino acids lipase breaks down fats found in most dairy products, nuts, oils, and meat cellulase breaks down cellulose, plant fiber; not found in humans `
