Enzymes Ticket Out the Door

Master enzyme function and factors affecting their activity with our engaging worksheet!

A chemical reaction is a process that changes one set of chemicals, the reactants into another set of chemicals, the products.Every chemical reaction needs energy to get started, and that starting energy is called the activation energy.A catalystis a substance that speeds up the rate of a chemical reaction. Catalysts work by loweringthe reaction’s activation energy. Enzymes are proteinsthat act as biological catalysts. Enzymes speed up chemical reactions by lowering activation energies.In an enzyme-catalyzed reaction, the reactant is known as the substrate. The substrate binds to a site on the enzyme called the active siteEnzymes are specificfor each reaction and are reusable. The item labeled A in the diagram below is the... reactant product active site enzyme The item labeled C in the diagram below is the... reactant product active site enzyme The item labeled D in the diagram below is the... reactant product active site enzyme Review the Graphs below to answer the following question:At what temperature range is enzymeA working the best? 0 - 20 degrees C 60 - 80 degrees C between 1 -3 around 45 and 0 degrees C 20 - 40 degrees C Review the Graphs below to answer the following question:At what temperature range is enzyme B working the best? 0 - 20 degrees C 60 - 80 degrees C between 1 -3 around 45 and 0 degrees C 20 - 40 degrees C Review the Graphs below to answer the following question:At what temperature would enzymeA be denatured(ineffective)? 0 - 20 degrees C 60 - 80 degrees C between 1 -3 around 45 and 0 degrees C 20 - 40 degrees C Review the Graphs below to answer the following question:Which enzyme would work better in our very acidic stomachs?
