Which compound is formed when Fructose 6-phosphate is converted in step 3?

Fructose 6-phosphate is an important intermediate in the glycolytic pathway and its conversion in step 3 is a key regulatory point in carbohydrate metabolism. The enzyme that catalyzes this reaction is phosphofructokinase-1 (PFK-1), which phosphorylates fructose 6-phosphate using ATP. This process results in the formation of fructose 1,6-bisphosphate.

Fructose 1,6-bisphosphate is a highly reactive compound that serves as a crucial substrate for subsequent reactions in glycolysis, ultimately leading to the production of energy in the form of ATP. This phosphorylation step is not only important for energy production but also helps to regulate the flow of carbon through the glycolytic pathway based on the energy needs of the cell.

In the context of the other options provided, they do not result from the direct conversion of fructose 6-phosphate in step 3 of glycolysis. For example, glucose 1-phosphate is involved in different metabolic pathways, glyceraldehyde 3-phosphate is derived later in the glycolytic pathway, and glyceraldehyde 1,3-bisphosphate is formed after additional steps. Therefore, the formation of fructose 1
