What is Aerobic Respiration?The breaking down of sugar to produceenergy where oxygen is present. C 6 H 12 O6 + 6O2 Enzymes → 6CO2 + 6 H 2 O + 36 ATP Glucose + Oxygen Carbon Dioxide + Water+ Energy
When We Exercise…After two minutes of exercise, the body respondsby supplying working muscles with oxygen.When oxygen is present, glucose can becompletely broken down into carbon dioxide andwater
Anaerobic Respiration refers tothe oxidation of molecules in the absence of oxygen to produce energy It is also known As Fermentation
What happens whenfermentation occurs? 1.In Muscle Cells- During intensive activities, the oxygen in the muscle tissue is decreased to an extent that aerobic respiration does not occur at a sufficient rate. so, there is a buildup of lactic acid and your muscles get tired. Equation for anaerobic respiration in your muscles: C6H12O6 (Glucose) -> 2C3H6O3 (Lactic Acid) + Small amount of energy
2. In Yeast- The fermentation end product is ethyl alcohol, and CO2
Chemical Formula for Anaerobic Respiration in yeastEnergy + Glucose → Ethanol + Carbon Dioxide + Energy Yeast
Lab ExperimentCarbon dioxide can be tested using lime water Calcium hydroxide, Ca(OH)2.
So Who gives more energy? Aerobic or Anaerobic respiration ? Hint: Go back to the formula
