Question

Define enzyme and write its mechanism.

Hint:

Enzymes work on the lock-and-key mechanism or induced-fit model to catalyze reactions efficiently.

Answer 1

Step 1: Definition of Enzyme Enzymes are biological catalysts that speed up biochemical reactions without being consumed. Step 2: Mechanism of Enzyme Action 1. Substrate Binding: The substrate binds to the enzyme's active site.
2. Formation of Enzyme-Substrate Complex: Temporary association forms.
3. Catalysis: The enzyme converts substrate into product. 4. Product Release: The enzyme releases the product and remains unchanged.
