Which of the following statements about metabolism are true? catabolism is the process in which complex substances are broken down, yielding a net output of energy. metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways. the overall process of metabolism involves the breakdown of polymeric biomolecules and complex lipids to monomers and less complex fats, followed by further degradation to inorganic compounds. all organisms derive raw materials and energy from organic molecules, such as glucose.

Answer;Catabolism is the process in which complex substances are broken down, yielding a net output of energyMetabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.Explanation;Metabolism is the chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized. Catabolism is the metabolic breakdown of complex molecules into simpler ones, resulting in a release of energy. These reactions are exothermic. Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. Anabolic reactions are endothermic.
