anaerobic + aerobic respiration

• aerobic respiration is more efficient that anaerobic
• most reactions in aerobic respiration happens in the mitochondria
• aerobic respiration :

  glucose + oxygen ---> carbon dioxide + water

  C6H12O2 + O2 ---> 6CO2 + 6H20
• In anaerobic respiration the incomplete breakdown of glucose makes lactic acid
• anaerobic respiration in muscle cells :

  glucose ---> lactic acid
• aerobic respiration produces more energy because in anaerobic respiration the glucose isnt fully oxidised
• anaearobic respiration in plant and yeast cells produce ethanol and carbon diooxide instead of lactic acid

  glucose ---> ethanol + carbon dioxide
• yeast are single-celled organisms
• anaerobic respiration in yeast cells is called fermentation
• after anaerobic respiration you will have oxygen debt
• oxygen debt is the amount of extra oxygen your body needs to react with the build up of lactic acid
• the blood flowing through the muscles transports the lactic acid to the liver to convert it back to glucose. this is another way the body gets rid of the lactic acid
