Why is ATP required for glycolysis? ATP is used to convert DHAP into G3P. ATP is used to reduce NAD^+ to NADH. ATP is used to convert PEP into pyruvic acid. ATP makes it easier to break apart glucose into two three-carbon molecules.

TP is required for glycolysis because it is used to convert DHAP into G3P. Glycolysis is the process of breaking down glucose into two three-carbon molecules called pyruvate. During this process, ATP is used to convert dihydroxyacetone phosphate (DHAP) into glyceraldehyde-3-phosphate (G3P), which is an important intermediate in glycolysis. ATP is also used in other steps of glycolysis to provide the energy needed for the reactions to occur.
