Question

During glycolysis, glucose is broken down into two isomeric forms of molecules called ?

Answer 1

During glycolysis, glucose is broken down into two molecules of **pyruvate**. Initially, glucose (a six-carbon sugar) is converted into two three-carbon molecules through a series of enzymatic reactions. These three-carbon molecules are actually in the form of **glyceraldehyde-3-phosphate (G3P)**, and **dihydroxyacetone phosphate (DHAP)**, which are isomers of each other. However, ultimately, both forms will contribute to the production of pyruvate.
