Imagine you want to get rich by genetically engineering tobacco plants to produce acai berry juice. To do so, you insert the genes for each of the enzymes in the hypothetical acai juice synthesis pathway, the first step of which is conversion of glucose to fructose. Your challenge is, if the concentration of acai berry juice gets too high, it is toxic to the cell. Furthermore, it would be nice to save glucose as the starting material for other processes....
