| Lesson Topic: explain that during oxidative phosphorylation: hydrogen atoms split into protons and energetic electrons, energetic electrons release energy as they pass through the electron transport chain (details of carriers are not expected), the released energy |
Learning Objective/s:
- Describe how hydrogen atoms are split into protons and electrons during oxidative phosphorylation.
- Explain how the energy released by electrons moving through the ETC drives proton pumping.
- Illustrate how the proton gradient powers ATP synthase to produce ATP.
- Identify the role of oxygen as the final electron acceptor.
- Predict the effect of inhibiting the ETC on overall ATP production.
|
Materials Needed:
- Projector or interactive whiteboard
- PowerPoint slides or digital diagram of a mitochondrion
- Handout with summary table and flow‑chart worksheet
- Physical model of a mitochondrion (plastic or 3‑D printed)
- Clicker/quiz cards for formative checks
- Exit‑ticket slips
|
Introduction:
Begin with a quick think‑pair‑share: what would happen to a cell’s energy supply if oxygen were removed? Review that NADH and FADH₂ deliver hydrogen atoms into the mitochondrion. Today’s success criteria are to trace the fate of those hydrogen atoms and explain how their energy ends up as ATP.
|
Lesson Structure:
- Do‑now (5’) – Students label a blank mitochondrion diagram (matrix, inner membrane, inter‑membrane space).
- Mini‑lecture (10’) – Explain hydrogen atom split, electron flow, and proton pumping using slides.
- Guided walkthrough (12’) – Walk through the step‑by‑step overview; students complete a flow‑chart worksheet.
- Interactive simulation (8’) – Online ETC animation; students note where energy is released.
- Think‑pair‑share (5’) – Discuss why oxygen is essential; teacher confirms with the reduction equation.
- Formative check (5’) – Clicker quiz on key steps and ATP synthesis.
|
Conclusion:
Summarise how the split hydrogen atoms generate a proton gradient that drives ATP synthase. Students complete an exit ticket stating one surprising insight and one lingering question. For homework, they write a short paragraph linking oxidative phosphorylation to the overall process of cellular respiration.
