Biomolecules & Enzyme Review

Match the macromolecule to the monomer: Nucleic Acid Nucleotides Lipids Fatty Acids + glycerol Proteins Amino Acid Carbohydrates Monosaccharides Fill in the blanks with the correct answer. 1. A nucleic acid is made up a monomer called a(n) nucleotide.2. Examples of nucleic acids are DNA There are 20 different types of amino acids that can be found in protein.4. The type of biomolecule that makes up part of the cell membrane is a lipid.5. An enzyme, a molecule that speeds up a reaction, is an example of a protein.6. Glycogen, an energy source of animals, is an example of a carbohydrate.7. A small building block of a macromolecule is called a monomer, which joins together to form large molecules called polymers. Match the polysaccharides correctly. 1. Starch is food and energy for plants.2. Animals use Glycogen for energy.3. Chitin is used for structure of insects and fungi.4. Cellulose makes up the plant cell wall. Which macromolecule does NOT contain nitrogen? Protein Carbohydrate Nucleic Acid Which macromolecule does NOT provide energy? Carbs Lipids Nucleic Acid Sort the description into the correct column. Carbohydrate Made up of monosaccharides Lactose and cellulose are an example MAIN energy source of humans sugars and starches glycogen, chitin Lipid Made up of fatty acids and glycerol Commonly called oils and fats Makes up the cell membrane long term energy storage insulation and protection Protein Contain peptide bonds Forms blood, skin, hair and muscles Made up of amino acids Makes enzymes fights disease (antibodies) Nucleic Acid Contains phosphate DNA Made up of nucleotides genetic information Match: Nucleotide Amino Acid Triglyceride Monosaccharide Enzymes are what type of macromolecule? lipid nucleic acid protein carbohydrates Functions of Enzymes Watch the video and answer the questions below. Fill in the blanks based on the information in the video. Enzymes increase the rate of the reaction.Enzymes are not consumed in a reaction.Enzymes can break molecules apart, build, or add molecules and even rearrange molecules.Enzymes lower the activation energy of a reaction.The change in energy remains the same between the start and end of the chemical reaction.Enzymes cause a reaction rate to happen faster. Parts of an Enzyme Reaction Label the parts of an enzyme reaction below using the word bank provided. Spelling counts! One word will be used twice.ProductEnzymeSubstrateActive SiteEnzyme-Substrate Complex Substrate Enzyme Enzyme-Substrate Complex Enzyme Product Active Site Vocabulary Match the word to the correct description. enzyme a protein catalyst that speeds up a chemical reaction catalyst a substance that speeds up a chemical reaction optimum temperature or pH at which the enzyme works best denature when the active site of an enzyme changes so that the substrate no longer fits. substrate the reactant that binds to the active site on an enzyme Use the graphs below to answer the following question.What is the optimal temperature range for enzyme A? 0-20 degrees C 70-80 degrees C between 1-3 30-40 degrees C 50 degrees C Use the graphs below to answer the following question.At what temperature would enzyme B be denatured (ineffective)? 75 degrees C 60 degrees C 100 degrees C 55 degress C Use the graphs below to answer the following question.Your stomach is very acidic with a pH between one and three.
