The correct order of steps involved in the formation of an enzyme-substrate complex is:
enzyme binds to substrate at active site > enzyme-substrate complex forms > chemical reaction takes place > products are released.
Explanation:
- Enzyme binds to substrate at active site: This is the first step where the enzyme interacts with its specific substrate, fitting together like a lock and key.
- Enzyme-substrate complex forms: Once the substrate is bound, the combination of the enzyme and substrate is known as the enzyme-substrate complex.
- Chemical reaction takes place: After the formation of the complex, the enzyme catalyzes a chemical reaction, converting the substrate into products.
- Products are released: Finally, once the reaction occurs, the products are released from the active site of the enzyme, allowing the enzyme to be free to catalyze another reaction.
Hence, the focus of the process starts with the binding of the substrate and ends with the release of products, making the first response the correct one.
