Show Answers:

  1. What is an inorganic compound?
    • Compound that:
    • Usually lacks carbon and is structurally simple
    • Relatively small and cannot be used BY CELLS to preform complex biological functions
    • Formed by ionic and covalent bonds
  2. What are some examples of inorganic compounds in the human body? What % of human body are they?
    • Water, many salts, acids and bases.
    • Water = 55-60% of human body
    • Other inorganic compounds = 1-2% of human body
  3. What is an organic compound.
    • Compound that:
    • Contains carbon and usually hydrogen
    • Most large and made of long chains of carbon atoms
    • ALWAYS HAVE covalent bonds
  4. What % of the body are organic compounds?
  5. What is a solution?
    A solvent with a salute dissolved in it.
  6. What is a solvent? (in relation to water)
    A substance that can dissolve ionized or polar substances.
  7. What is a solute? (in relation to water)
    A substance with ionic and/or polar covalent bonds that dissolves in a solvent.
  8. Describe hydrophilic
    • Hydro- water, philic- loving
    • A substance that dissolves easy in water.
    • Dissolves because the substance is ionic or polar.
    • EX: Sugar (sucrose), Salt
  9. Describe hydrophobic
    • hydro- water, phobic- fearing
    • A substance that does not dissolve in water.
    • Consists of mainly non-polar covalent bonds.
    • EX: animal fats, vegetable oils.
  10. Why is water so important for metabolic reactions?
    • Dissolves many molecules
    • Allows dissolved reactants to collide and form products
    • Dissolves wastes products which allows them so they can be expelled
  11. What is hydrolysis?
    • A decomposition reaction in which H2O (water) is broken down and chemically bonded with parts of a larger molecule that is also broken down.
    • A decomposition reactions break down large molecules into smaller molecules by the addition of water molecules.
  12. What is dehydration synthesis? (Polymerization, condensation)
    • A synthesis reaction in which water is one of the products.
    • Larger molecules are formed by having each others O's and H2's bond to form water, so they can bond to form larger molecules.
  13. What is somethings heat capacity?
    • The amount of heat energy required to change the temperature of something.
    • Its ability to absorb or release heat relative to its own temperature.
  14. Why does water have a large heat capacity? Why is its thermal properties so important for the body?
    • When water is heated some of that energy goes towards breaking its hydrogen bonds which means less is used to increase the motion of water molecules.
    • It helps the body maintain homeostasis by lessening the impact of environmental temperature changes.
    • When water (sweat) evaporates from the skin, it takes away a large amount of heat that was in the water.
