Final answer:
The enzyme responsible for breaking down fructose-1,6-bisphosphate into two trioses during glycolysis is aldolase. It cleaves fructose-1,6-bisphosphate into dihydroxyacetone phosphate and glyceraldehyde-3-phosphate, essential for subsequent ATP production.
The correct option is E) aldolase.
Step-by-step explanation:
The enzyme used to break down fructose-1,6-bisphosphate into two trioses is called aldolase. During the glycolytic pathway, aldolase plays a crucial role. It catalyzes the cleavage of fructose-1,6-bisphosphate into two three-carbon molecules: dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (G-3-P). This reaction is vital as it leads to the eventual production of ATP, which the cell uses as an energy source. The correct option in this case is E) aldolase, which is fundamental in the metabolic pathway known as glycolysis.
The enzyme phosphogluco-isomerase is responsible for converting glucose-6-phosphate into fructose-6-phosphate, an isomer that allows the eventual split of the sugar into two three-carbon molecules. Following this, phosphofructokinase phosphorylates fructose-6-phosphate, leading to the formation of fructose-1-6-bisphosphate, setting the stage for the action of aldolase.
Therefore, the correct option, as mentioned above, is E) aldolase.
