What Binds to an enzyme and plays a role in catalysis?

A substrate binds to an enzyme and plays a crucial role in catalysis. The enzyme's active site specifically recognizes and interacts with the substrate, facilitating the conversion of the substrate into products through various mechanisms. This binding often involves non-covalent interactions, such as hydrogen bonds and hydrophobic interactions, which stabilize the enzyme-substrate complex and enhance the reaction rate. Additionally, cofactors or coenzymes may also assist in the catalytic process by providing essential chemical groups or facilitating electron transfer.
