Detailed explanation-1: -Catabolic pathway: large molecules are broken down into small ones. Energy is typically released. Image credit: OpenStax Biology. Anabolic pathways build complex molecules from simpler ones and typically need an input of energy.

Detailed explanation-2: -Anabolism is the process by which the body utilizes the energy released by catabolism to synthesize complex molecules. These complex molecules are then utilized to form cellular structures that are formed from small and simple precursors that act as building blocks.

Detailed explanation-3: -Catabolic Reactions. Catabolic reactions break down large organic molecules into smaller molecules, releasing the energy contained in the chemical bonds.
