Enzymes

Enzymes are biological catalysts that speed up reactions by lowering activation energy. They work with substrates using a lock and key mechanism, where the substrate fits into the enzyme's active site. Enzymes are specific to substrates and can either break down or build up molecules. Factors like substrate concentration, pH, and temperature affect enzyme activity. Enzymes are used in various biological processes and industries, such as in washing powders and juice production.
