ENZYME ACTION: Lock and key compared to Induced Fit Model in lowering activation energy.
Learn the lock and key compared to the induced fit model. Learn how the induced fit model better explains how enzymes lower the activation energy. See how this theory links to protein structure in A-level biology.

Have my year 9 biochem exam tomorrow and we need to know about the induced fit model. Your video helped me understand it a lot better . Thanks!

i dont think youll need to know this model that in depth atm in year 9
Thank you very much for this video , but I want more details about how to change the structure of the enzyme in the active site in the Kochland model induced fit . I mean how to change the sites of the acids amino to obtain a three-dimensional structure for structural integration with the substrate material. I searched, but I did not find sources on the internet.
nice explanation
Thanks a lot
One of the best videos on KZread

SLAYYYYYYYYYYY
miss, could you explain how come in the induced fit model the substrate bonds get weakened which causes the activation energy to be lowered? im finding it a bit hard to grasp the correlation between the two (the bonds being weakened which causes the activation energy to decrease)
@MissEstruchBiology

the active site moulding around the substrate puts tension of the bonds in the substrate
both lock and key and induced fit models are accepted models, and there are papers to show that both models are represented by different enzymes.

Hello, Thanks for highlighting this. My videos link to the AQA exam board and so follow what students need to know for this.
i hope i can use this in my psychopharmacology class ?

I thought the substrate was the one who change it's shape slightly 🤔

Hello 👋 its the enzyme that slightly changes to fit around the substrate to put a strain on the bonds so less energy is needed to break the bonds on the substrate.
Do we still need the lock and key model for AQA?

Aren't enzymes specific that's why the induced fit model isn't accepting 🤔🙄

@@jennipherchanda6266 They are specific. The induced-fit model doesn't change that. The enzyme is able to bind the substrate but the slight change in the shape of the active site is what causes the reaction, otherwise, you would just have two molecules binding together. The active site is technically complementary to the 'transition state' which is where the substrate is at its highest potential energy to react.
