Biomolecules Practice

Match the biomolecule on the left to its corresponding monomer on the right by clicking on one orange dot and dragging a line to the dot of its match: Nucleic Acid Nucleotides Lipids Fatty Acids + glycerol Proteins Amino Acid Carbohydrates Monosaccharides Click on the blanks to see a list of answer choices. Choose the answer that best fits the statement. The answers will not be used more than once. 1. A nucleic acid is made up of monomers called nucleotide.2. Examples of nucleic acids are DNA There are 20 different types of amino acids that can be found in protein.4. A carbon-hydrogen chain that makes up part of a lipid is called a fatty acid.5. An enzyme, a molecule that speeds up a reaction, is an example of a protein.6. Glycogen, a short term energy source in 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 prefixes to their meaning by connecting a dot on the left to one on the right: Mono- One Di- Two Poly- Many -ose Indicates a sugar -mer Part Are lipids soluble in water? Yes No Which macromolecule does NOT contain nitrogen? Protein Carbohydrate Nucleic Acid Which macromolecule does NOT provide energy? Carbohydrates Lipids Nucleic Acid Which is NOT an example of a lipid? Triglycerides Disaccharides Phospholipids What is NOT a polysaccharide? Phospholipid Starch Cellulose This is a an example of a... Monosaccharide Polysaccharide Disaccharide Sort the given descriptions by dragging and dropping them into the correct biomolecule section below. Carbohydrate Made up of monosaccharides Commonly called sugars Lactose and cellulose are an example Lipid Made up of fatty acids and glycerol Makes up the cell membrane Triglycerides for long-term energy Protein Forms blood, skin, hair and muscles Made up of amino acids Makes enzymes Nucleic Acid Contains phosphate DNA Made up of nucleotides Match the terms on the left with those on the right by creating a line between the images and their corresponding : Nucleotide Amino Acid Fatty Acid Monosaccharide
