On the reactant side, on the product side, we produce a ribose phyphosphate. We generate the NADPH molecules, the reducing agents that can be used in a variety of biphynthetic processes as discussed in that section. And we also generate carbon dioxide. 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.
