Show Answers:

  1. metabolism
    all chemicals reactions and physical workings of a cell
  2. anabolism
    also called biosynthesis any process that results in synthesis of cell molecules and structures

    small molecules into large molecules
  3. catabolism
    the breakdown of bonds of larger molecules in smaller
  4. enzymes
    biological catalyst chemicals that increase the rate of a chemical reaction without becoming part of the product or being consumed in the reaction

    work by decreasing the activation
  5. activation energy
    the amount of energy which must be over come for a reaacton
  6. apoenzyme
    activated enzyme
  7. coenzyme
    non-protein molecules
  8. simple enzyme
    consist of protein alone
  9. conjugated enzyme
    contain protein and non-protein molecules
  10. exoenzyme
    enzyme secreated and work outside the cell
  11. denaturation
    the week bonds that maintain the native shape of the apoenzyme are broken
  12. competative inhibitors
    a molecule that resembles the enzyme is normal substrates, directly competing for that active site
  13. non-competative inhibitor
    a molecule that binds to the enzyme at a place other then the active site thus altering the shape of the active site indirectly
  14. exogonic reaction
    a reaction that releases energy as it goes fwd
  15. endergonic reaction
    a reaction that is driven fwd with tht the addition of energy
  16. oxidation/reduduction
    inportant in removing energy and transferring the other molecule to ultimatly make energy rich compound in organisms
  17. ATP yeilds
  18. phosphorlation
    to make ATP you must add phosphate to ADP
  19. how does phosphorlation occur
    series of redox reactions occurring during the final phase of the respitory pathway

    addint phophate directly
  20. ways to make ATP
    • aerobic respiration
    • fermentation
    • anaaerobic respiration
  21. aerobic respiration
    series of reactions that convert glucose to co2 and allows the cell to recover the amount of energy

    requires oxygen
  22. fermentation
    when cells use only the glycolysis scheme to imcompletly oxidize glucose
  23. anaerobic respiration
    uses ions other then fire oxygen as the final electron acceptor
