Question

Why is pentose phosphate pathway also called as a shunt pathway?​

Answer 1

Answer:

The pentose phosphate shunt pathway provides substrates for oxidative defense, biosynthetic reactions, and nucleotide biosynthesis. The oxidative component of the pathway generates 2NADPH+2 H+ in successive oxidation reactions starting with glucose-6-P and forming 6-P-gluconate (6PG), then ribulose-5-P (R5P)+CO2.

Answer 2

Answer:

The Hexose Monophosphate Shunt is also known as “Pentose Phosphate Pathway” (PPP). This is an alternative Glucose oxidation pathway. The hexose monophosphate pathway is used for the production of NADPH from NADP.

The NADPH is required for biosynthetic reactions such as fatty acid synthesis, cholesterol synthesis, drug reduction, and as a cofactor for some non-synthetic enzymatic reactions. Pentose Phosphate Pathway is the alternative Glucose oxidative pathway.
