WebFeb 8, 2024 · Also, in the induced-fit model, it was stated that there are amino acids that aid the correct substrate to bind to the active site which leads to shaping of the active site to the complementary shape. Induced fit is the model such that structure of active site of enzyme can be easily changed after binding of enzyme and substrate.

WebEnzymes exhibit substrate specificity, meaning that they can only bind to certain substrates.
