<u>Explanation:</u>
- Reactants are the one that react together in a chemical equation. The product is the result formed due to the chemical reaction occurring between the reactants.
- For example if natural gas is burnt the methane and the oxygen are the reactants. The product produced due to the chemical reaction is Carbon dioxide and water as the product.
- For the production of ADP water acts with ATP to reduce Triphosphate to diphosphate. In this, it is the reactant and in chemical reaction the bonds are broken between the atoms and new bonds are produced between the products.
