During the reaction, the substrate will attach to the active site. After the reaction, the product will leave the enzyme complex.

During the reaction, the substrate will attach to the active site. After the reaction, the product will leave the enzyme complex.

During the reaction, the "substrate" will attach to the active site. After the reaction, the "product" will leave the enzyme complex.

To understand this concept, let's break it down:

1. Enzymes are biological molecules (usually proteins) that catalyze chemical reactions in living organisms. They work by binding to specific molecules, called substrates, and facilitating the conversion of these substrates into different molecules, known as products.

2. The active site is a specific region on the enzyme where the substrate molecules bind. It has a three-dimensional shape that complements the shape and chemical properties of the substrate, allowing for a precise fit.

3. During the reaction, the substrate molecules attach to the active site of the enzyme. The binding is temporary and reversible, forming an enzyme-substrate complex.

4. Once the enzyme-substrate complex is formed, the enzyme facilitates the conversion of the substrate into the product by lowering the activation energy required for the reaction to occur. This allows the reaction to proceed more rapidly.

5. After the reaction is complete, the product molecules, having undergone the chemical transformation, no longer fit within the active site. Therefore, they detach from the enzyme, leaving the enzyme free to bind to another substrate and catalyze another reaction.

In summary, substrates attach to the enzyme's active site during the reaction, forming an enzyme-substrate complex. After the reaction, the products detach from the active site, allowing the enzyme to be available for additional reactions.
