Enzymes: B1.2.6, B1.2.7, B1.2.8: AQA

Biology Unit 1: Chapter 2:

Pages 2.6, 2.7, 2.8 in the textbook, on chapter 2 unit 1. Check my powerpoint here which is based on these Q&A type revision notes.

I use the power point to revise (I have a whiteboard, so do lots of brainstorming, etc) and then use the documents to test myself. They might be a bit useless on their own.

1. Enzymes work by lowering the activation energy, allowing reactions to take place with lower
temperatures, and metabolic processes to occur rapidly.

2. Enzymes have an active site that is made up of few amino acids, like a depression within the molecule. The
subtstrate and enzyme combine neatly here,…
