22.1
Aerobic respiration
Releasing energy from glucose, the word summary, mitochondria, the limewater and warm-peas tests, and why plants respire too.
22.2
Breathing and respiration
Breathing isn't respiration: how oxygen and glucose reach the cells, how carbon dioxide leaves, and why breathing and heart rate rise in exercise.
22.3
Anaerobic respiration
Respiration without oxygen in hard exercise, lactic acid, the oxygen debt, and how aerobic and anaerobic respiration compare.
22.4
Fermentation
Anaerobic respiration in yeast: the word summary, the balloon test, bread, brewing, temperature, and the three ways to respire.
