Paper 1 — Bioenergetics (overview)
Big-picture map of photosynthesis and respiration, including required practical concepts.
What’s in Bioenergetics (Paper 1)
- Photosynthesis (equation, limiting factors)
- Required practical concepts (rate of photosynthesis)
- Aerobic respiration
- Anaerobic respiration (animals + plants)
- Response to exercise (oxygen debt, lactic acid)
How it’s tested
- Required practical method + variables
- Graph interpretation (rate)
- Extended responses (4–6 marks)
