| Lesson Topic: outline the need for energy in living organisms, as illustrated by active transport, movement and anabolic reactions, such as those occurring in DNA replication and protein synthesis |
Learning Objective/s:
- Describe why living organisms require energy for active transport, mechanical movement, and anabolic reactions.
- Explain how ATP hydrolysis powers active transport, muscle contraction, DNA replication, and protein synthesis.
- Analyse the ATP/GTP consumption of key cellular processes and relate it to cellular function.
- Apply knowledge of energy coupling to predict the effects of altered ATP availability.
|
Materials Needed:
- Projector and PowerPoint slides
- Handout containing the summary table of ATP use
- Cell‑membrane and ATP molecule models
- Worksheets with case‑study questions
- Clickers or online quiz platform for quick checks
- Short video clips of muscle contraction and Na⁺/K⁺‑ATPase
|
Introduction:
Begin with a 30‑second video of a sprinter powering a race to hook students on the idea that all movement needs energy. Ask them what they already know about ATP as the cell’s “energy currency.” State that by the end of the lesson they will be able to explain how ATP fuels active transport, movement and the synthesis of DNA and proteins, and will demonstrate this understanding through a short exit ticket.
|
Lesson Structure:
- Do‑Now (5'): Quick clicker quiz on ATP structure and basic hydrolysis.
- Mini‑lecture (10'): Overview of why energy is needed; introduce ATP coupling to active transport, movement, and anabolism with slide graphics.
- Group analysis (15'): Students examine the summary table, calculate approximate ATP costs for a chosen process, and discuss why those costs matter.
- Demonstration (10'): Show video of Na⁺/K⁺‑ATPase and muscle fibre contraction; relate observations to ATP use.
- Guided practice (10'): Worksheet on the ATP‑dependent steps of DNA replication and protein synthesis; teacher circulates for support.
- Check for Understanding (5'): Exit‑ticket question – “Give one example of how a cell would be affected if ATP were unavailable for a specific process.”
|
Conclusion:
Recap the four major ways cells use ATP and emphasize the link between energy supply and cellular function. Collect exit tickets to gauge understanding, and assign a homework task: create a concept map linking ATP hydrolysis to at least three cellular processes covered today.
