What is substrate?

A substrate is a substance or material on which an enzyme acts to catalyze a chemical reaction. In other words, it is the molecule that an enzyme binds to and acts upon to produce a specific product. Substrates are typically specific to the enzyme that catalyzes the reaction, and the enzyme-substrate complex is a key step in the enzyme-catalyzed reaction process.

Substrate is a substance or surface that provides a place where a reaction can take place. In the context of enzymes, a substrate is the molecule that the enzyme catalyzes. The enzyme binds to the substrate and lowers the activation energy of the reaction, making it more likely to occur. The substrate is then converted into products, which are released from the enzyme.
