Test your knowledge on the shunt pathway, also known as the pentose phosphate pathway or hexose monophosphate shunt. Learn about this alternative pathway for glucose oxidation, where about 10% of glucose per day enters. Explore how three molecules of glucose-6-phosphate result in the production of CO2 and 5 carbon residues.
