What by using enzymes catalyze chemical reactions?

Enzymes are biological catalysts that accelerate chemical reactions by lowering the activation energy required for the reaction to occur. They achieve this by binding to specific substrates at their active sites, forming an enzyme-substrate complex that facilitates the conversion of substrates into products. This process is highly specific, as each enzyme typically catalyzes only one type of reaction or acts on a particular substrate. Consequently, enzymes play a crucial role in various biological processes, including metabolism and cellular signaling.
