Label the diagram. SPELLING COUNTS!Use the word bank for correct spelling. Use the following words to label the Enzyme picture:enzyme (hint: used twice)substratesactive siteenzyme-substrate complexproduct enzyme enzyme-substrate complex active site enzyme product substrates Look in your notes or watch the lecture again to find the answers. Enzymes are proteins that reduce the activation energy of a chemical reaction and reduce the rate of the reaction. Enzymes are necessary to maintain homeostasis (internal balance).Substrates are the substances that undergo a chemical reaction caused by the enzyme. Most enzyme names have the ending -ase. Enzymes are which type of biomolecule? carbohydrate lipid protein nucleic acid An enzyme is not used up when catalyzing a reaction lowers the activation energy of a reaction bonds with a substrate molecule at the active site all of the above none of the above Sort the statements into TRUE statements or FALSE statements. True enzymes are substrate specific enzymes speed up chemical reactions False enzymes change shape after a chemical reaction one enzyme can be used for many types of chemical reactions Extreme temperature changes can cause enzymes to denature and _ the rate of the reaction. increase decrease not change Examine the diagram. Which curve shows the effect an enzyme has on a chemical reaction? red curve black curve Refer to the diagram above. How was the enzyme able to make the reaction happen faster? the enzyme reduced the activation energy needed for the reaction to take place the enzyme increased the activation energy needed for the reaction to take place Match the parts of the enzyme-substrate complex with the appropriate description. product substance formed from the substrate during the chemical reaction active site location on the surface of an enzyme that binds to the substrate enzyme protein that speeds up chemical reactions substrate substance that an enzyme acts upon activation energy amount of energy required for a chemical reaction to occur The relationship between an enzyme and their substrates can best be described as salt and pepper apples and oranges lock and key left and right
