A catabolic process is a process by which complex compounds are broken down into simpler components or molecules and releases energy. Whereas, the anabolic process creates complex molecules broken down in catabolism by utilizing energy and these molecules remain in the organism to be used again.Photosynthesis is an anabolic process as it combines carbon dioxide and water in the presence of solar energy to form a complex substance called glucose in the leaves.Respiration is a catabolic process as it breaks down complex molecules into simpler ones with release of energy in the form of ATP molecule.
