How does the structure of an enzyme molecule affect its function in biological processes?

The structure of an enzyme molecule is crucial for its function in biological processes. Enzymes have specific shapes that allow them to bind to specific molecules, called substrates, and facilitate chemical reactions. This specificity is due to the precise arrangement of amino acids in the enzyme's active site. Changes in the enzyme's structure can affect its ability to bind to substrates and catalyze reactions, ultimately impacting the efficiency of biological processes.
