oxaloacetate

fructose-1,6-bisphosphate

glyceraldehyde-3-phosphate

dihydroxyacetone phosphate

Next problem

Verified step by step guidance

Understand the pathways: Glycolysis is the process of breaking down glucose into pyruvate, while gluconeogenesis is the synthesis of glucose from non-carbohydrate precursors. Both pathways share some common metabolites.

Identify common metabolites: In both glycolysis and gluconeogenesis, certain intermediates are shared. These include fructose-1,6-bisphosphate, glyceraldehyde-3-phosphate, and dihydroxyacetone phosphate.

Recognize unique metabolites: Oxaloacetate is a key intermediate in gluconeogenesis but is not part of the glycolysis pathway. It is involved in the conversion of pyruvate to phosphoenolpyruvate in gluconeogenesis.

Compare the given options: List the metabolites provided in the problem and determine which are common to both pathways and which are not.

Conclude the exception: Based on the comparison, identify oxaloacetate as the metabolite that is not present in both glycolysis and gluconeogenesis, making it the correct answer to the problem.
