| Text | Different sequences of {{c1::amino acids}} make up different {{c1::proteins}} and form different {{c1::shapes}}. Enzymes are proteins; each enzyme’s active site has a {{c2::specific}} shape, allowing it to {{c3::bind}} to a specific substrate molecule to catalyze metabolic reactions. Antibodies also have a {{c2::specific}} shape, formed by a specific sequence of amino acids. This allows them to {{c3::bind}} to antigens on foreign pathogens to kill them.
