Enzmes

Enzymes are the compounds that make living organisms possible. All of the reactions that sustain life, such as cellular respiration, photosynthesis, and DNA translation and transcription, may happen without enzymes, but would happen infrequently and very slowly. Neither of these conditions are acceptable for sustaining life. By lowering the activation energy of these reactions, enzymes make them happen more quickly and frequently. Enzymes are currently the focus of scientific research in genetic engineering, agriculture, and waste disposal.
