Anabolism term refers to the synthesis of complex molecules from simpler ones and is endergonic in nature. Glycogenesis is the process by which glycogen is synthesised, by the addition of glucose molecules to form chains of glycogen for storage. This process is activated in the liver during rest periods following the Cori cycle and also activated by insulin in response to high glucose levels. Gluconeogenesis is the process of formation of glucose from non-carbohydrate. It is stimulated by glucagon and inhibited by insulin. It promotes glycogenesis and helps in storage of excessive blood glucose level as glycogen in the liver. Since in both, the process the synthesis of the complex molecule takes place they are anabolic reactions. Thus, the correct answer is option D.
