NEW (2016) AS-Level Biology - Enzyme Action

This lesson is designed for the NEW AQA AS-level Biology course, particularly the ‘Biological Molecules’ module.

A-Level lesson format: I teach in more of a lecture style compared to GCSE. In the majority of my A-level lessons the beginning portion of the lesson is mainly teacher-led, where students are expected to take notes onto a handout/in their books. This is then mixed in with student-led activities, as well as questions and exam prep.

You will find some of my slides have blank spaces for you to add more detail/descriptions/explanations. If you look at the ‘Notes’ section underneath each of these slides, you will find additional content which you can add in as you teach!

This lesson begins with an introduction to enzymes and a starter discussion to review the structure of amino acids and the quaternary structure of proteins.
Students will then watch a short video and work independently to answer review questions from the video. The following slide offers brief answers to these questions so that students may self-assess.

The lesson then progresses through a series of lecture style slides explaining enzyme involvement in chemical reactions, the structure of enzymes, and the two models of enzyme action.

Following these slides, students have an opportunity to work in pairs to teach each other the two enzyme action models. The information for each student in their pairs is provided as the last slide in the lesson. Students should take notes on both models in their books and are encouraged to sketch a ‘cartoon strip’ style diagram as an extra challenge.

Students are then asked to practise two exam style questions, worth 7 marks and 2 marks respectively. The slide following these questions offers a marking scheme so students may self-assess. After a short discussion on these two questions, students are tasked with a third exam question on enzyme action. This exam style question is attached as an additional resource for students to fill in the blank spaces as a worksheet which requires students to define important terms related to enzyme action.

As a plenary task to complete the lesson and check understanding, students are asked to complete one of four sentences in their books.

All resources are included. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)
