Summary Introduction

To explain: The balanced equation for the catabolism of six molecules of G6P by the pentose phosphate pathway followed by the conversion of Ribulose-5-phosphate back to G6P by gluconeogenesis.

Concept introduction:

The pentose phosphate pathway is a direct oxidative pathway that takes place in the cytosol of a cell. This pathway consists of two phases, namely oxidative phase and non-oxidative phase. In oxidative phase, when glucose-6-phosphate (G6P) is oxidized into ribose, 5- phosphate generates NADPH. During the non-oxidative phase, the interconvertion of sugar molecules takes place.
