Detailed explanation-1: -Enzymes are proteins that act upon substrate molecules and decrease the activation energy necessary for a chemical reaction to occur by stabilizing the transition state. This stabilization speeds up reaction rates and makes them happen at physiologically significant rates.

Detailed explanation-2: -To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme’s substrates. In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces.

Detailed explanation-3: -The name of the molecule on which an enzyme works is called a. Substrate. This molecule can also be called as a reactant. For example, in glycolysis, the substrate molecule during the first step is glucose.
