This is not in your book. This is how the rate of a chemical reaction is increased by increasing the temperature. The temperature of an object is held in the vibration of the molecules. Enzyme definition: A catalyst (increases the rate of a chemical reaction). But enzymes are a special type of catalyst, which are not used up during the reaction. The substrate is in black. The green and blue are amino acids in the carboxypepetidase enzyme. As the substrate binds in the ACTIVE SITE binding pocket, the enzyme is designed to change shape (tertiary structure, conformation). This is called INDUCED FIT. The shifting shape is due to changes in many noncovalent reactions within the protein kind of like a Rube Goldberg invention: As the protein changes shape, the shifting shape causes the substrate to be under chemical stress leading to the TRANSITION STATE. A competitive inhibitor slows an enzyme down by binding to the active site. A noncompetitive inhibitor slows an enzyme down by binding to a site that is different than the active site. Chapter 9: Metabolism There are three ways eucaryotic cells burn glucose: (occurs in most animals) (occurs in all animals) (occurs in some animals, e.g., yeast) 45/60 = = is the number of questions you got right. 60 is the total number of questions. 75 is your percentage out of is the points you got for your notes (10 points maximum). 85 is your total score and is circled. Compare that with what other students got.
