Explanation down below...


Anabolic reactions construct larger molecules from smaller ones. An example of this is reduction reactions. In these types of reactions, hydrogen is added to another molecule in order to store energy. Anabolic reactions require energy.

Catabolic reactions involve the breaking down of larger organic molecules, which releases energy. An example of this is oxidative reactions, where the removal of hydrogen occurs. When energy is stored in a molecule produced by an anabolic reaction, the energy can be released again using catabolic reactions.

Hydrolysis is a type of reaction which requires water to break down a molecule; it is, therefore, a catabolic reaction. A good example of this is the breakdown of polysaccharides which requires water as one of the reactants.

Condensation (dehydration synthesis) is a type of reaction which produces water; it is, therefore, a metabolic reaction. A good example of this is the formation of polysaccharides through the removal of water.https://chem.libretexts.org/Textbook_Maps/General_Chemistry/Map%3A_Chemistry_(Averill_and_Eldredge)/24%3A_Organic_Compounds/24.6_The_Molecules_of_Life

Hope this helped !! :D
