Why HMP shunt called as shunt?

The HMP shunt, or Hexose Monophosphate shunt, is referred to as a "shunt" because it diverts glucose-6-phosphate from the glycolytic pathway to generate NADPH and ribose-5-phosphate. This pathway provides essential reducing power for biOSynthetic reactions and helps in maintaining cellular redox balance. The term "shunt" highlights its role in redirecting metabolic flow away from energy production towards biOSynthetic and antioxidant functions.
