Question | Answer |
---|---|
Definition of respiration | RELEASING energy from glucose |
Where respiration takes place | All cells of all organisms |
Releasing energy from glucose using oxygen | Aerobic respiration |
Word equation for aerobic respiration | Glucose + oxygen > carbon dioxide + water |
Releasing energy from glucose without using oxygen | Anaerobic respiration |
Word equation for anaerobic respiration | Glucose > lactic acid |
Consequence of lactic acid | |
Consequence of lactic acid in muscles | Fatigue and cramps |
How the body gets rid of lactic acid | Liver breaks it down using oxygen |
Name given to increased requirement for oxygen after anaerobic respiration | Oxygen debt |
Name for anaerobic respiration in yeast | Fermentation |
Word equation for fermentation | Glucose > alcohol + carbon dioxide |
Uses of fermentation | Brewing alcohol and bread making |
Why aerobic respiration is better than anaerobic | More energy released per molecule of glucose, no lactic acid produced |
