  4. Prokaryotic Cells
  5. Ionic bonds
  1. a some atoms lose or gain electrons to form ions. attraction between ions of opposite charge form ionic bonds
  2. b 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
  3. c are parts of a molecule that participate in a chemical reaction

5 Multiple choice questions

  1. houses chromosomes (DNA + chromatin - protein), and nucleolus - site of ribosome parts assembly, in an membrane = nuclear envelope
  2. 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
  3. small 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.
  4. reads the genes and helps make proteins
  5. Combine to form compounds. Are formed of atoms.
