put the steps of enzyme activity in order from first to last using the drop down menu beside each step. the chemical reaction occurs. a substrate enters the active site of enzyme. new substances called products are formed. the enzyme and the substrate bind to form the enzyme - substrate complex.

Explanation:

To determine the order of enzyme activity, we follow the basic mechanism of enzyme - substrate interaction:

1. First, the substrate needs to enter the active site of the enzyme. This is the initial step where the substrate approaches and gets into the region of the enzyme where the reaction will take place.
2. Next, the enzyme and the substrate bind to form the enzyme - substrate complex. This binding is a crucial step as it brings the substrate in the right orientation for the reaction to occur.
3. Then, the chemical reaction occurs. Once the enzyme - substrate complex is formed, the enzyme catalyzes the reaction, converting the substrate into products.
4. Finally, new substances called "products" are formed. After the reaction, the products are released from the enzyme - substrate complex.

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.
