Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources, such as amino acids and glycerol. It involves the use of intermediates from glycolysis, the Krebs cycle, and the breakdown of lipids and proteins. It is a biosynthetic pathway, thus making option D correct as it encompasses all aspects of gluconeogenesis accurately.
