5 Matching questions

  1. Atomic Number=
  2. Golgi Apparatus (Eukaryotic cells)
  3. Ionic bonds
  4. Vacuoles (Eukaryotic cells)
  5. hydrogen bonds
  1. a some atoms lose or gain electrons to form ions. attraction between ions of opposite charge form ionic bonds
  2. b number of protons
  3. c some molecules have charged areas - this makes them polar. Polar areas of molecules can bond with polar areas of other molecules to form weak bonds called hydrogen bonds, hydrogen bonds make water cohesive
  4. d receives packages such as transport vesicles on one side, modifies products, then repackages in new transport vesicles for other sites
  5. e larger vesicles, membranous sacs that help in digestion, storage, or water removal

5 Multiple choice questions

  1. molecules of carbon + hydrogen
  2. =Mass number=protons+ neutrons
  3. elements with the same atomic number, different mass numbers.
  4. 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
  5. houses chromosomes (DNA + chromatin - protein), and nucleolus - site of ribosome parts assembly, in an membrane = nuclear envelope

5 True/False questions

  1. Lysosomes (Eukaryotic cells)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


  2. proteinsmall nitrogen containing molecules, amino acids, are joined to form dipeptides which are joined to form polypeptides which may be joined to other polypeptides to from proteins. Proteins have unique 3 dimensional shapes or configurations that enable them to function as enzymes to catalyze reactions and function in other active ways.


  3. Endoplasmic Reticulum (Eukaryotic cells)a system of interconnected membranes that run throughout the cell for synthesis, storage, and transport of products


  4. nucleic acidstwo types, DNA and RNA. DNA forms our genes, RNA reads the genes and helps make proteins, __________ _____ are composed of joined monomers called nucleotides. These nucleotides are composed of a sugar - deoxyribose (DNA) or ribose (RNA), a nitrogenous base (adenine, thymine, cytosine, guanine, or uracil), and a phosphate group


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