  3. c 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
  4. d forms our genes,
  5. e number of protons

5 Multiple Choice Questions

  1. have a membrane that surrounds nuclear material
    Components: Nucleus, Cytoplasm, Organelles, hydrophilic heads, hydrophobic tails,
  2. 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
  3. these are non-polar, hydrocarbons, which are composed of fat molecules. Fat = glycerol + fatty acid. _______ are 1) important components of cell membranes (phospho_______), 2) molecules (steroids) that regulate cell function, and 3) molecules (waxes) that protect other cells
  4. found in plants and animals, chemical energy in food such as sugars is converted to an energy source useable in cells called ATP, ___________ have a membrane, an intermembrane space and matrix. Reactions take place in the matrix
  5. 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
