Enzymes are special proteins that act as catalysts in our bodies, speeding up chemical reactions. They help break down food, build new molecules, and support various biological processes. Each enzyme is specific to a particular reaction, much like a key fits into a lock. This specificity ensures that the right reactions happen at the right time. In addition to digestion, enzymes play a crucial role in many areas of life, including medicine, biotechnology, and industry. For example, enzymes are used in laundry detergents to break down stains, making them an essential part of everyday products. Their efficiency and specificity make them vital for both natural and human-made processes.
