Here's why:

* Function: Enzymes are biological catalysts, meaning they speed up chemical reactions in living organisms without being consumed in the process.

* Structure: Enzymes are typically proteins, though some are RNA molecules (ribozymes).

* Naming Convention: The "-ase" suffix is a standard way to name enzymes. It often indicates the type of reaction the enzyme catalyzes or the substrate it acts upon.

Examples of Enzymes:

* Lactase: Breaks down lactose (milk sugar)

* DNA polymerase: Builds DNA molecules

* Protease: Breaks down proteins

* Lipase: Breaks down fats
