Enzymes and Digestion – AQA GCSE Biology Lesson

Enzymes and Digestion: a complete, no-prep PowerPoint lesson for AQA GCSE Biology and Combined Science (Trilogy), with exam-style questions, tasks and answers – no worksheets needed.

Covers the enzymes half of AQA 4.2.2.1 (the human digestive system): enzymes as biological catalysts, the lock and key model, how temperature and pH affect enzymes, and the digestive enzymes – carbohydrases such as amylase, proteases and lipases – including where they are made and what they break food down into.

I split 4.2.2.1 into two lessons. The previous lesson, Digestive System & Principles of Organisation, covers the digestive system and its functions. Calculating rates of reaction is in the required practical lesson, RPs: Food Tests, Amylase Enzymes and pH. All three lessons are in my Digestion and Enzymes bundle: https://www.tes.com/teaching-resource/enzymes-and-digestion-mini-bundle-12979895

As a Secondary Science teacher, Deputy Headteacher, writer and examiner for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam-style questions.

My lessons are designed to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy.

What’s Included:
• Teaching notes
• Starter / Do Now Activity
• Explanation slides in “chunked” sections with animated diagrams.
• Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers.
• Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards.
• Answers for all questions
• All easily editable to adapt to your teaching or to use in existing lessons.
• Slightly humorous, at points, if you like that sort of thing.

The lesson was written for AQA GCSE Science / Biology but is very likely to be applicable to other exam specifications.
