Anaerobic respiration

• Anerobic respiration does not require oxygen

  Word equation for anaerobic respiration in human

  • Glucose -> lactic acid

  Word equation for anaerobic respiration in yeast

  • Glucose -> carbon dioxide + ethanol
• Describe what occur during intense exercise?

  During intense exercise, increasing heart rate and breathing rate is not enough to supply oxygen to the muscle quickly enough. So anaerobic repsiration occurs where glucose is broken down without oxygen. The waste product is lactic acid which builds up in muscle leading to cramps.
• EPOC(oxygen debt)

  -excess ,post-exercise, oxygen, consumption

  How does it work

  -After exercising, a person continue to breathe more deeply and rapidly than when at rest.

  Why

  -To take in the additional oxygen to pay back for the oxygen debt

  -Oxygen is then use to break down lactic acid into carbon dioxide and water using oxygen.

  -Remove excesss carbon dioxide from the body
