Final answer:
Glycerol-demanding fructose metabolic pathway in the liver is gluconeogenesis, a process by which glucose is synthesized from non-carbohydrate sources. Glycerol is converted to dihydroxyacetone phosphate and then to glucose-6-phosphate in this pathway.
Step-by-step explanation:
The glycerol-demanding fructose metabolic pathway in the liver is called gluconeogenesis. Gluconeogenesis is the process by which glucose is synthesized from non-carbohydrate sources, such as glycerol, lactate, and amino acids. In this pathway, glycerol is converted to dihydroxyacetone phosphate, which then enters glycolysis and is converted to glucose-6-phosphate.
