Detailed explanation-1: -Catabolic reactions involve breaking down larger and complex molecules into smaller and simpler molecules releasing energy in the process. Anabolic reactions, on the other hand, involves building complex/macromolecules from simple and smaller molecules.
Detailed explanation-2: -Anabolic reactions require energy. Catabolic reactions release energy. Not all energetically favored reactions are spontaneous. Many times some energy of activation needs to be added.
Detailed explanation-3: -Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones.
Detailed explanation-4: -Catabolism, which is the process of digestion and break down complex chemicals into simpler molecules.
Detailed explanation-5: -The metabolic pathway that releases energy by breaking down complex molecules into smaller, simpler compounds is called catabolism.
