Here's why:
* Enzymes are proteins: Enzymes are biological catalysts made of proteins.
* Proteins are made of amino acids: Proteins are long chains of amino acids linked together.
* Amino acid sequence determines structure and function: The specific order of amino acids in a protein chain determines its three-dimensional shape and, ultimately, its function.
* Different amino acid sequences lead to different enzymes: Each enzyme has a unique amino acid sequence that gives it its specific catalytic properties.
Think of it like this: Imagine you have a set of building blocks (amino acids). The order in which you put them together (amino acid sequence) determines the shape and function of the final structure (the enzyme).
