  • RESPIRATION
    • AEROBIC
      • Uses glucose and sugar. Releases Energy.
        • The energy that is released may be used for a number of things...
          • Build larger molecules from smaller ones and amino acids from sugars nitrates and other nutrients  which then combine to form proteins. (In plants)
          • Allow muscles to contract.
          • Maintain steady body temperature.
      • Takes place in BOTH animals & plants.
        • MOST of the reactions in respiration happen in the mitochondria which is in the cytoplasm of the cell.
      • GLUCOSE + OXYGEN > CARBON DIOXIDE + WATER + ENERGY
        • CO2 is taken by the blood to the lungs and breathed out.
        • Glucose and oxygen are brought to the respiring cells by the bloodstream.
        • Water passes into the blood and is lost as sweat, moist breath and urine.

          • Allow muscles to contract.
          • Maintain steady body temperature.
    • ANAEROBIC
      • If there is not enough oxygen reaching your muscles then they use anaerobic respiration to obtain energy.
        • It is the incomplete breakdown of glucose.
        • Produces Lactic Acid.
          • If muscles carry out vigorous activity for a long time they become fatigued, stop contracting and eventually hurt.
            • This is caused by the build up of Lactic Acid
          • Blood flowing through the muscles will remove Lactic Acid.
          • HT: Lactic Acid must be oxidised into CO2 and Water. The Oxygen needed to do this is called Oxygen Debt.
      • GLUCOSE > ENERGY + LACTIC ACID
        • Glucose from the blood stream.
        • A small amount of energy is produced quickly and used for explosive activity.
        • Lactic Acid accumulates in muscles makes them feel rubbery.
  • GLUCOSE + OXYGEN > CARBON DIOXIDE + WATER + ENERGY
    • CO2 is taken by the blood to the lungs and breathed out.
    • Glucose and oxygen are brought to the respiring cells by the bloodstream.
    • Water passes into the blood and is lost as sweat, moist breath and urine.
