Detailed explanation-1: -The induced-fit model was first proposed by Koshland in 1958 to explain the protein conformational changes in the binding process. This model suggests that an enzyme, when binding with its substrate, optimizes the interface through physical interactions to form the final complex structure.

Detailed explanation-2: -Explanation: The lock and key model states that the active site of an enzyme precisely fits a specific substrate. The induced fit model states that the active site of an enzyme will undergo a conformational change when binding a substrate, to improve the fit.

Detailed explanation-3: -Lock-and-key model is a model for enzyme-substrate interaction suggesting that the enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another. Enzymes are highly specific. They must bind to a specific substrate before they can catalyze a chemical reaction.

Detailed explanation-4: -Catalysis is when the substrate is changed. It could be broken down or combined with another molecule to make something new. It will break or build chemical bonds. When done, you will have the enzyme/products complex.

Detailed explanation-5: -The lock-and-key theory of enzyme action proposes that the enzyme’s active site and the shape of the substrate molecule are complementary to one another. This allows the substrate to fit into the enzyme, like how a key would fit into a lock. If the substrate doesn’t fit, then the enzyme will not act on it.
