PPT-Enzymes Web Quest Enzymes are proteins that speed up chemical reactions in the body.

1 What are enzymes Each enzyme has only one specific reaction it can perform 2 How many different reactions can a single enzyme perform Yes the same enzyme molecule can be used over and over. Chapter 2: Section 2.5. 1. Objectives. SWBAT explain the effect of a catalyst on activation energy. . SWBAT describe how enzymes regulate chemical reactions. . and maintain homeostasis.. 2. Starter: How can this be possible. Warm up. Grab warm up and complete. We will be putting this into your . journal. When you are done with your warm up look over your Vocab 1-1, you have a . quiz today. Biomolecule review. Cellulose, a structural component of the cell wall of plants and some forms of algae, is mainly used to produce paper and cardboard products. Cellulose would be an example of which type of biomolecule. Apoenzymes. , . Holoenzyme. , . Abzymes. , . Synzyme. , . Ribozyme. , . Extremozyme. , Historical Development in . Enzymology. , .

Everything that happens in a cell. Growth. Reproduction. Interaction with the environment. Response to stimuli. Is the result of a chemical reaction.. A chemical reaction is a change in the arrangement. protein. !. Enzymes are . Biological . catalysts . that . increase. . the rate of metabolic reactions.. Since enzymes speed up chemical reaction rates, what are they called?. Catalyst- . A substance . Chemical Reactions. :. A . chemical reaction . is a process that changes one set of chemicals into another by rearranging chemical bonds. The elements you start with are . reactants. The elements you end with are . The Digestive System. Amazing Facts . . We make 1-3 pints of saliva a day.. The average male will eat about 50 tons of food to sustain weight of 150 pounds. A horse’s intestines are about 89 feet long. THINK ABOUT IT . Living things are made up of chemical compounds, but chemistry isn’t just what life is made . of—chemistry is also what life does. . . Everything that happens in an organism. —its growth, its interaction with the environment, its reproduction, and even its movement. Most matter in your body that is NOT water is made of organic compounds.. 4 Principle Classes of . Organic Compounds. : . Carbohydrates. Lipids. Proteins. Nucleic Acids. Carbohydrates. Made up of Carbon, Hydrogen, and Oxygen atoms. Enzymes. Back when we discussed proteins, we learned that one critical function of protein was to speed up chemical reactions.. Enzymes. are the proteins that increase the rate of chemical reactions. In order for chemical reactions to take place, . enzymes . must be present to help . speed up . the reaction.. Chemical bonds connect atoms. to make . molecules. .. Chemical . reactions. can do two things:. that . catalyze. (. i.e.. , . increase or decrease the rates. of) . chemical reactions. .. . In enzymatic reactions, the . molecules. at the beginning of the process are called . substrates. , and they are converted into different molecules, called the . Today’s Objectives. Describe a general enzyme-catalyzed reaction. Discuss the relation of temperature and pH to rate of reaction in an enzyme-catalyzed reaction. Explain how chemical reactions are affected by enzymes. enzymes. . . The . substance converted by an enzyme is called a . substrate. , and a substance resulting from the conversion of the substrate is called the . product. . . The . enzyme is not consumed during the reaction catalyzed by it, so one enzyme molecule is involved in the conversion of many substrate molecules .
