Question

What is the next step in the process after a substrate enters the active site of an enzyme?
The chemical reaction occurs.
New substances called products are formed.
The enzyme and the substrate bind to form the enzyme-substrate complex.
The enzyme and the products bind to form the enzyme-products complex.

The enzyme and the substrate bind to form the enzyme–substrate complex.

Explanation: once the substrate fits into the enzyme's active site, they form the enzyme–substrate complex; then the chemical reaction occurs, producing products.
