Inside GCSE Biology: Bioenergetics — Quick Burst Practice
complete the photosynthesis equation and name where it happens, read a limiting-factor graph, recall aerobic respiration in the mitochondria, sort lactic acid from fermentation, and finish on oxygen debt and metabolism. About 10 minutes.
Learning objectives
- photosynthesis — the word equation, the chloroplast and why it is endothermic;
- limiting factors — reading a rate graph and naming which factor is limiting;
- aerobic respiration — the equation, the mitochondria and why it is exothermic;
- anaerobic respiration — lactic acid in muscle and fermentation (ethanol + carbon dioxide) in yeast;
- oxygen debt and metabolism — the response to exercise and the meaning of metabolism.
Activities in this book
Round 1 — Photosynthesis Fire
photosynthesis happens in the chloroplasts, which hold the green pigment chlorophyll. It is endothermic — it takes in energy from light. Word equation: carbon dioxide + water → glucose + oxygen.
Round 2 — Limiting Factor Blitz
a limiting factor is the one in shortest supply that holds back the rate. The three limiting factors of photosynthesis are light intensity, carbon dioxide concentration and temperature.
Round 3 — Aerobic Respiration Sprint
aerobic respiration uses oxygen and mostly happens in the mitochondria. It is exothermic. Word equation: glucose + oxygen → carbon dioxide + water.
Round 4 — Anaerobic & Fermentation
without oxygen, muscle cells do anaerobic respiration to make lactic acid. In yeast and plants this is called fermentation: glucose → ethanol + carbon dioxide. Anaerobic respiration transfers less energy per glucose.
Round 5 — Oxygen Debt & Metabolism
after hard exercise the body needs extra oxygen — the oxygen debt — to break down the lactic acid that built up. Metabolism is the sum of all the reactions in a cell or the whole body.
Suggestions for teaching
- Keep it quick. Set a timer — the point of a quick burst is fluent recall, not extended working.
- Little and often. Use these rounds as a warm-up or exit ticket rather than a full lesson.
- Drill the equations. Get both the photosynthesis and aerobic respiration word equations automatic.
What you’ll learn
