The structural changes that … WebApr 9, 2024 · The induced-fit model expands upon the lock-and-key model by describing a more dynamic interaction between enzyme and substrate. As the enzyme and substrate come together, their interaction causes a mild shift in the enzyme’s structure that confirms an ideal binding arrangement between the enzyme and the transition state of the …

WebThe classic model for the enzyme-substrate interaction is the induced fit model. This model proposes that the initial interaction between enzyme and substrate is relatively weak, but that these weak interactions rapidly … WebThe induced fit model allows for any substrate to bind with a specific enzyme regardless on the size whereas the lock and key model only allows a specific substrate.
