Detailed explanation-1: -The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.

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.

Detailed explanation-3: -A substrate is a molecule that an enzyme reacts with. The enzyme’s active site, or the location where weak bonds between the two molecules can form, is loaded with a substrate.

Detailed explanation-4: -The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site. There are two theories explaining the enzyme-substrate interaction. In the lock-and-key model, the active site of an enzyme is precisely shaped to hold specific substrates.
