Exam points
- interpret respirometer bubble movement or ethanol-concentration trends as evidence of respiration rate
- predict that respiration rate rises towards an optimum temperature and falls above it as enzymes denature
- explain low-temperature results using low kinetic energy and fewer effective collisions
