Item description

Enzymes as biological catalysts is a professionally created, visually stimulating PowerPoint presentation/PDF that will not just save teachers lots of valuable lesson preparation time but also help students to understand and/or revise this essential and fundamental topic in biology. Suitable for students in Years 10 – 12, Enzymes as biological catalysts can easily be used as both an introduction to a new unit, or as revision.

Enzymes as biological catalysts covers the following:

  • what are enzymes?

  • how do enzymes make reactions go faster?

  • differences between the ‘lock-and-key’ and ‘induced-fit’ models of enzyme action

  • factors that affect enzyme activity: temperature, pH, enzyme concentration, substrate concentration and inhibition (reversible and irreversible)

  • reversible inhibition: competitive and non-competitive

  • enzyme helpers: organic and inorganic cofactors

  • organic cofactors: coenzymes and prosthetic groups

The content in Enzymes as biological catalysts is explained clearly and includes good detail (without being overwhelming). It also uses simple language that is generally easier to understand than the average textbook, making it accessible to as many of your students as possible. There are lots of colorful, easy-to-follow diagrams to assist the visual learner and facilitate good class discussion.

I hope you and your students find this product useful and that you enjoy using it as much as I enjoyed creating it!
