Enzymes belong to the class of biomolecules known as proteins. They are biological catalysts that speed up chemical reactions in the body without being consumed in the process.
Proteins are made up of long chains of amino acids, which fold into specific shapes that determine their function. The unique structure of each enzyme allows it to interact with specific substrates and catalyze reactions effectively. Enzymes play crucial roles in various biological processes, including digestion, metabolism, and DNA replication.
In summary, enzymes are specialized proteins that facilitate biochemical reactions, making them essential for life.
