Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The substance doing the reacting (water in hydrolysis for example) during a chemical reaction
A
Reactant
B
Substrate
C
Catalyst
D
Products
Explanation: 

Detailed explanation-1: -The reactants other than water, and the products of hydrolysis, may be neutral molecules (as in most hydrolysis reactions involving chemicals) or ionic molecules (charged species), as in hydrolysis reactions of salts, acids, and bases.

Detailed explanation-2: -Some examples of hydrolysis include dissolving a salt of a weak acid or base in water or dissolving sulphuric acid in water where hydronium and bisulfate compounds are formed. Hydrolysis also helps in breaking down proteins, fats, and complex carbohydrates in food.

Detailed explanation-3: -In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro” = water and “lysis” = break) involves adding water to one large molecule to break it into multiple smaller molecules.

Detailed explanation-4: -The reacting water molecules are split into hydrogen (H+) and hydroxide (OH−) ions, which react with and break up (or “lyse") the other reacting compound. The term hydrolysis is also applied to the electrolysis of water (that is, breaking up of water molecules by an electric current) to produce hydrogen and oxygen.

Detailed explanation-5: -Hydrolysis of water is decomposition reaction as water decompose into oxygen and hydrogen due to electric current being passed through water.
