Intro to Metabolism EXAM 2

  1. energy
    • ability to promote change or do work
    • potential
    •  - chemical - in bonds of molecules
    • kinetic
  2. spontaneous
    • exergonic
    • input/release energy
  3. endergonic
    make energy
  4. metabolic pathway
    • enzymatically catalyzed chemical reactions in a cell
    • determined by enzymes
  5. substrates turn into
    products
  6. catalyst
    speed up rate of reaction (ie enzymes and ribozymes)
  7. activation energy
    energy needed to start reaction
  8. how to overcome activation energy
    • heat
    • enzymes
  9. enzyme features
    • active site
    • substrate
    • enzyme
  10. enzyme parts
    • apoenzyme - protien
    • cofactor - non protein (NAD, FAD, etc)
    • haloenzyme - apoenzme and cofactor
  11. factor that affects enzyme
    • Temperature
    • pH
    • Substrate concentration
    • Inhibitors
  12. inhibition
    • competition binds to active site
    • noncompetition binds to allosteric site which changes enzyme shape
    • feedback - end product inhibitss first enzyme
  13. oxidation
    lose electrons (OIL)
  14. reducing
    gain electrons
  15. energy intermediates
    • create energy by losing electrons
    • ie NAHD
  16. ATP > energy endergonic reaction (muscle contract) > ADP > energy from exergonic reaction cellular reaction
    ok
  17. ways to make ATP
    • substrate level phosphorylation (force P on)
    • oxidative phosphorylation (chemeosmosis and ETC)
    • phosphorylation
