Exam points
- Define cellular respiration as enzyme-controlled, stepwise oxidation of organic compounds that releases energy for ATP production.
- Relate aerobic respiration to oxygen use, electron acceptance, carbon dioxide release and ATP generation across respiration stages.
- Interpret respiration and metabolite evidence to compare aerobic/anaerobic energy release and identify substrates used by cells.
