Aerobic Respiration

  • digestive system, lungs and circulation all work to provide body with glucose and oxygen needed for respiration 
  • during that, glucose reacts with oxygen, this releases energy, this energy vital for everything that goes on in body
  • carbon dioxide are produced as waste products, called aerobic respiration as uses oxygen from the air
  • glucose + oxygen ----> carbon dioixde + water (+ energy)
  • C6H12O6 + 6O2 ----> 6CO2 + 6H2O + (energy)

Mitochondria: Site of Respiration

  • aerobic respiration has a lot of chemical reactions, each one is controlled by a different enzyme, most take place in mitochondria of cells
  • mitochondria are tiny rod shaped organelles, have folded inner membrane, provides large surface area for enzymes 
  • no. of mitochondria in cell, shows active the cell is
