In most of the enzymes studied thus far, a cleft, or indentation, into which the substrate fits is found at the active…. WebApr 12, 2024 · Enzymes go to work on molecules called substrates, which bind to a part of the enzyme known as the active site. Two theories explain this interaction. The lock and key theory suggests that the active site is specifically shaped to hold certain substrates. The induced-fit model posits that each component alters its shape to connect.
