Suppose there is a glycolytic-like pathway carried out by an alien species that uses analogous enyzme mechanisms to convert an 8-carbon sugar (see structure ① below) to two 4 carbon fragments and then to a pyruvate analog. The conversion of the 8-carbon bisphosphate (compound ④ below) to the two 4 carbon fragments (compouds and D) is a reversible reaction. Using the mechanism of fructose-1,6-bisphosphate aldolase (Type I) as your model, draw the mechanism of the reaction shown in Scheme 2, the conversion of the 4 carbon fragments (compounds D and O) to the 8-carbon bisphosphate (compound ④.
