So we see that in the first phase, the oxidative phase, the cell breaks down glucose into a five carbon sugar, a pento sugar and also releases a carbon dioxide and generates the much needed NADPH. Now, in the second stage, in the second phase, that's the non oxidative phase. And what happens is we have three carbon, four carbon, five carbon, six carbon and seven carbon sugars are interconverted from one to the other. And if we have an excess of five carbon sugars what this pathway does is it basically transforms the five carbon sugars into intermediates that can be part of the glycolytic pathway. And we'll discuss that in much more detail in the lectures to come. So ultimately, the pentose phosphate pathway gives our body a way to actually digest.
