glucose + oxygen =carbon dioxide + water

Question 9

anaerobic respiration equation (muscles)

Answer 9

glucose = lactic acid

Question 10

anaerobic respiration (plants & yeast)

Answer 10

glucose = ethanol + carbon dioxide

Question 11

fermentation

Answer 11

anaerobic respiration in yeast

Question 12

oxygen debt

Answer 12

the amount of extra oxygen your body needs to react with the build up of lactic acid and remove it from cells.
