Detailed explanation-1: -Catabolic pathways involve the breakdown of complex molecules into simpler ones and typically release energy. Energy stored in the bonds of complex molecules, such as glucose and fats, is released in catabolic pathways.
Detailed explanation-2: -Catabolism is the process of breaking down complex molecules into simpler molecules. Catabolic reactions often employ hydrolysis in order to break down complex molecules by adding a molecule of water to the simple molecules that are the products.
Detailed explanation-3: -Catabolic pathways involve the degradation (or breakdown) of complex molecules into simpler ones. Molecular energy stored in the bonds of complex molecules is released in catabolic pathways and harvested in such a way that it can be used to produce ATP.
Detailed explanation-4: -Catabolic reactions break down complex chemicals into simpler ones and are associated with energy release. Anabolic processes build complex molecules out of simpler ones and require energy.
