Detailed explanation-1: -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-2: -An enzyme attracts substrates to its active site, catalyzes the chemical reaction by which products are formed, and then allows the products to dissociate (separate from the enzyme surface). The combination formed by an enzyme and its substrates is called the enzyme–substrate complex.

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. An enzyme substrate complex is formed, and the enzyme’s pressures on the substrate drive it to react and become the planned reaction’s result.

Detailed explanation-4: -Substrate. This molecule can also be called as a reactant. For example, in glycolysis, the substrate molecule during the first step is glucose.

Detailed explanation-5: -Substrate: The starting material (other than enzyme or coenzyme) for an enzymatic chemical reaction.
