A lesson on aerobic and anaerobic respiration built around a marathon hook and a yeast practical. It explains respiration with and without oxygen, what happens in muscles during exercise, and the equation for anaerobic respiration in yeast, then sets up an experiment measuring carbon dioxide from different drinks.
What this presentation covers
- why living things break down sugar
- aerobic respiration
- what happens in muscles during exercise
- anaerobic respiration and lactic acid
- fermentation in yeast
- a practical using a carbon dioxide sensor to compare drinks
