WebApr 9, 2024 · A theory to explain the mechanism of enzymatic reactions, in which it is proposed that the enzyme and substrate (s) bind temporarily to form an enzyme–substrate complex. The binding site on the enzyme is known as the ‘active site’ and is structurally complementary to the substrate (s). Thus the enzyme and substrate (s) are said to fit ... http://chemistry.elmhurst.edu/vchembook/571lockkey.html

WebMay 28, 2024 · In the lock and key model, the enzyme and the substrate have three-dimensional shapes that fit each other. The induced fit model proposes enzyme molecules can change their shape, depending on the interaction with the substrate. In this model, the enzyme and sometimes the substrate change shape as they interact until the active site … WebLock and Key Theory: The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer.
