5 Matching questions

  1. Levels of Protein structure
  2. RNA
  3. Endoplasmic Reticulum (Eukaryotic cells)
  4. Vacuoles (Eukaryotic cells)
  5. Atoms
  1. a Primary structure = sequence of amino acids
    Secondary structure = coiling to form an alpha helix or folding to form a pleated sheet - hydrogen bonding may be involved
    Tertiary structure - Overall, 3 - D shape, usually described as fibrous or globular
    Quaternary structure - many proteins have multiple peptide chains or subunits - how these fit together is called quaternary structure
  2. b larger vesicles, membranous sacs that help in digestion, storage, or water removal
  3. c Protons, Neutrons, electrons (subatomic particles).
  4. d a biosynthetic factory, two forms, smooth and rough - Rough - studded with ribosomes, small RNA structures where proteins are manufactured, Smooth - lack ribosomes, wall contains enzymes that make phospholipids, steroids, fatty acids, detoxify poisons, and store minerals used for muscle contraction -________ packages products in tiny sacs called transport vesicles that bud-off
  5. e reads the genes and helps make proteins

5 Multiple choice questions

  1. a system of interconnected membranes that run throughout the cell for synthesis, storage, and transport of products
  2. molecules of carbon + hydrogen
  3. ibers that run through the cell providing support, movement, anchorage and movement of organelles, 3 types - microfilaments, intermediate filaments, microtubules - the microtubule organizing center is called the centriole
  4. hydrolytic enzymes are manufactured by the ER sent to the Golgi for finishing and repackaging in sacs called _________, ___________ merge with food vacuoles to digest food or destroy invading organisms -Abnormal __________ can cause diseases include Tay-Sachs - inability to break down lipids resulting in damage to nerves and brain
  5. lack a membrane enclosed nucleus
    Nucleoid region, Ribosomes, Plasma membrane, Cell wall, Capsule, Pili, Flagella

5 True/False questions

  1. functional groupsare parts of a molecule that participate in a chemical reaction

          

  2. Ionic bondssome atoms lose or gain electrons to form ions. attraction between ions of opposite charge form ionic bonds

          

  3. Nucleus (Eukaryotic cells)larger vesicles, membranous sacs that help in digestion, storage, or water removal

          

  4. Elementsdetermine chemical properties of atoms = how it will react (bond) with other atoms

          

  5. Eukaryotic Cellshave a membrane that surrounds nuclear material
    Components: Nucleus, Cytoplasm, Organelles, hydrophilic heads, hydrophobic tails,
