WebTwo models currently exist to explain how an enzyme and its substrate interact. One model, called the lock and key model, suggests that an enzyme is like a lock, and its substrate is like a key. The shape of the active site on the enzyme exactly fits the shape of the substrate. A second model, called the induced fit model, suggests that the ... WebJan 3, 1995 · This theory of induced fit extends the lock-and-key principle that Emil Fischer proposed exactly 100 years ago. The new theory proposed by D. E. Koshland, Jr. in 1958 allows one to explain regulation and cooperative effects, and adds some new specificity principles as well. Citing Literature. Volume 33, Issue 23-24.
