Respiration
- Uses of energy
- muscle contraction
- protein synthesis
- active transport
- body temperature
- Yeast investigation
- vary temperature
- count CO₂ bubbles
- control variables
- Aerobic respiration
- uses oxygen
- glucose + oxygen → CO₂ + water
- Anaerobic respiration
- no oxygen
- much less energy
- yeast: alcohol + CO₂
- muscles: lactic acid
- Balanced equationsSupplement
- C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
- C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
- Oxygen debtSupplement
- lactic acid builds up
- fast heart rate
- deeper breathing
- liver: aerobic respiration
