Explanation:

To determine the correct order of enzyme activity steps, we recall the enzyme - substrate interaction process:

1. First, a substrate must enter the active site of the enzyme. This is the initial step where the reactant (substrate) approaches the enzyme's active site.
2. Next, the enzyme and the substrate bind to form the enzyme - substrate complex. After the substrate is in the active site, the binding occurs to set up for the reaction.
3. Then, the chemical reaction occurs. Once the enzyme - substrate complex is formed, the enzyme catalyzes the reaction of the substrate.
4. Finally, new substances called “products” are formed. The reaction results in the formation of products, which then dissociate from the enzyme.

So the correct order from first to last is:

1. A substrate enters the active site of enzyme.
2. The enzyme and the substrate bind to form the enzyme - substrate complex.
3. The chemical reaction occurs.
4. New substances called “products” are formed.

Answer:

1. A substrate enters the active site of enzyme.
2. The enzyme and the substrate bind to form the enzyme - substrate complex.
3. The chemical reaction occurs.
4. New substances called “products” are formed.
