The flashcards below were created by user tjtolman on FreezingBlue Flashcards. What would you like to do?


  1. Anaerobic Respiration
    • -No Oxygen
    • -Inorganic molecule accepts electrons (nitrates, sulfates)
    • -Bacteria (soil breakdown) Breaks down into nitrogen gas and hydrogen sulfide and producing 2 ATP
  2. Fermentation
    • No Oxygen
    • Organic molecules accept electrons

    • Animals: Glucose breaks down into lactic acid producing 2 atp
    • -Muscle Soreness

    • Yeast: Glucose breaks down into ethanol and CO2 producing 2 atp molecules
    • - Bread and alchoholic beverages
  3. Aerobic Respiration:
    • Oxygen required
    • Oxygen accepts electrons
    • Breaks down into H2O and CO2 producing 36-38 ATP
  4. Rate of Aerobic Respiration:
    • Body Temp Regulation
    • Environmental Tempertures
    • Mass (Body Size)
  5. Endotherms
    • Warm Blooded
    • -maintain a constant body temperture, HIGHER metabolic rates.

    • -HIGHER metabolic rate in COLD environments.
    • -LOWER metabolic rate in WARM environments.
  6. Ectotherm:
    • Cold Blooded
    • -Body temp is affected by the external temp., LOWER metabolic rates.
    • - LOWER metabolic rates in COLD environments.
    • -HIGHER metabolic rates in WARM environments.
  7. Surface area to volume ratio: (SA/V)
    Surface area: 2(LW)+2(LH)+2(WH)

    Volume: (L)(W)(H)

    THE GREATER THE RATIO THE HIGHER THE RESPIRATORY RATE.
  8. Cellular Respiration Review
  9. Enzymes
    Proteins fold into different Motifs

    • Denature (altered chemical structure)
    • -pH
    • -Temp
    • -Ionic concentrations
  10. Biological catalyst
    Allows a chemical reaction to go faster, but is not used up in reaction.
  11. Activation Energy
    The energy that must be processed by a molecule in order for it to undergo a specific chemical reaction.
  12. Biological Catalyst/Activation Energy (graph)
  13. Endergonic reactons:
    The products contain more than the reactants, and the extra energy must be supplied for the reaction to proceed.
  14. Endergonic Reactions (graph):
  15. Exergonic Reactions:
    Products contain less energy than the reactants, and the excess energy is released.
  16. Exergonic Reactions (graph):
  17. Rate of enxymatic reactions depend on:
    • Temp
    • pH
    • Concentration
  18. Respiration rate per gram body weight
    cc O2/(min x body mass)
  19. concentration of enzyme and substrate:
    increasing concentration will increase rate of reaction
  20. Regulatory molecules:
    Allosteric site (coordinating change in active site)

    inhibitors: binds to active site and blocks it or binds somewhere else causing inactive configuration.
