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.
So, the first option is the correct sequence. The steps can be summarized as follows:
- The enzyme binds to the substrate at its active site.
- This binding leads to the formation of an enzyme-substrate complex.
- The enzyme facilitates a chemical reaction, converting the substrate into products.
- The products are released, and the enzyme is free to bind to another substrate molecule.
The other options listed do not accurately reflect the correct sequential steps in this enzymatic process.
