What is a substrate? a molecule that changes state a place where the reaction occurs a place on the product where the enzyme fits a reactant that is catalyzed by an enzyme

A reactant that is catalyzed by an enzyme.

Explanation:

The substrate is the substance or molecule over which an enzymes works during a biochemical reaction. The substrate attach itself to the active site of the enzyme and the enzyme- substrate complex is formed. The substrate is then transformed into products, which get released from the active site of the enzyme. The active site becomes free to accept another substrate molecule to be transformed into product. The enzyme exhibit catalytic property which facilitates the conversion of the substrate into the product.
