| Lesson Topic: Describe active transport as the movement of particles through a cell membrane from a region of lower concentration to a region of higher concentration, using energy from respiration. |
Learning Objective/s:
- Describe the process of active transport and how it moves particles against a concentration gradient.
- Explain the role of ATP produced by cellular respiration in powering active transport.
- Differentiate between primary and secondary active transport mechanisms with relevant examples.
- Illustrate the Na⁺/K⁺‑ATPase cycle and glucose‑Na⁺ co‑transport using labelled diagrams.
|
Materials Needed:
- Projector or interactive whiteboard
- PowerPoint/slide deck on active transport
- Handouts of Na⁺/K⁺‑ATPase and co‑transport diagrams
- Worksheet with comparison table and short questions
- Model or printable cut‑outs of a cell membrane (optional)
- Markers and chart paper for group summaries
|
Introduction:
Begin with a quick demonstration: ask students to imagine pushing a ball uphill versus letting it roll downhill. Review that passive diffusion moves substances down their gradient, while active transport moves them up, requiring energy. State that by the end of the lesson they will be able to describe how ATP from respiration fuels this uphill movement.
|
Lesson Structure:
- Do‑now (5'): Students answer a short question on diffusion vs. active transport on the board.
- Mini‑lecture (10'): Present definition, energy link, and ATP role using slides.
- Interactive diagram activity (10'): In groups, label the Na⁺/K⁺‑pump cycle on handouts.
- Guided inquiry (10'): Explore secondary active transport with the glucose‑Na⁺ example; teacher asks probing questions.
- Comparison table completion (8'): Students fill a table contrasting passive and active transport.
- Quick check (5'): Exit ticket – one sentence explaining why ATP is needed for active transport.
|
Conclusion:
Summarise that active transport moves substances against a gradient using ATP derived from respiration, highlighting primary and secondary mechanisms. Invite a few students to share their exit‑ticket responses for immediate feedback. Assign homework: create a labelled diagram of either the Na⁺/K⁺‑pump or the glucose‑Na⁺ co‑transport.
