Anaerobic Respiration
无氧呼吸
Description
Explain anaerobic respiration in animals as the incomplete breakdown of glucose to lactic acid when oxygen is in short supply, causing muscle fatigue; contrast this with aerobic respiration in terms of energy yield and products
Mastery Evidence
- Writes the word equation for anaerobic respiration in animals
- Explains why lactic acid causes muscle pain and fatigue
- Compares the energy released by aerobic and anaerobic respiration
- Explains oxygen debt and recovery after vigorous exercise
Assessment Prompt
If your child sprinted as fast as they could and their legs started to burn and ache afterwards, could they explain what's happening inside their muscles — why there isn't enough oxygen, and what the body produces instead?
