Detailed explanation-1: -substrate: A reactant in a chemical reaction is called a substrate when acted upon by an enzyme. induced fit: Proposes that the initial interaction between enzyme and substrate is relatively weak, but that these weak interactions rapidly induce conformational changes in the enzyme that strengthen binding.

Detailed explanation-2: -The key difference between substrate and product is that substrate is the staring material of a chemical reaction whereas product is the compound obtained after the completion of the reaction.

Detailed explanation-3: -Substrate: The starting material (other than enzyme or coenzyme) for an enzymatic chemical reaction.

Detailed explanation-4: -An enzyme substrate is the material on which the enzyme operates in biochemistry. The term substrate is sometimes used interchangeably with the term reactant, which refers to the molecule consumed in a chemical reaction.

Detailed explanation-5: -An enzyme does this by lowering the energy required for a reaction to take place between substrate molecules, or within one molecule. Once the reaction has taken place, the substrate is now chemically different, and is called the product.
