Splet21. jan. 2024 · Lock-and-key model is a model for enzyme-substrate interaction suggesting that the enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another. Enzymes are highly specific. They must bind to a specific substrate before they can catalyze a chemical reaction.

Spletdefinition Mechanism of enzyme action Lock and key hypothesis This is the simplest model to represent how an enzyme works. The substrate simply fits into the active site to form a reaction intermediate. Induced fit hypothesis In this model the enzyme molecule changes shape as the substrate molecules gets close. SpletThe lock and key hypothesis/ the induced fit model. The lock and key hypothesis explains how enzymes can be so specific with their substrates and the reactions they catalyse. It describes how the enzyme’s active site has a very unique shape that complements the shape of a specific substrate. They can therefore fit exactly together.

The place where these molecules fit is called the active site .
SpletLock and Key theory for the GCSE Biology syllabus. The lock and key theory is all to do with enzymes and what they do. Enzymes are extremely important as they allow chemical reactions to take place, and without that, processes such as digestion just wouldn’t happen. Enzymes speed up chemical reactions in our cells and work best when they are ...
