Concept explainers
Interpretation: To contrast the reactants in the first three steps of gluconeogenesis with the products in the last three steps of glycolysis.
Concept introduction: Glycolysis
In the gluconeogenesis pathway, glucose is produced from non-carbohydrate substances. The net overall equation for gluconeogenesis is as follows:
A reactant is defined as the substance that is initially present in the

- Name the substrate and the product of (a) glycolysis and (b) gluconeogenesis.arrow_forwardWhich statement best describes the reason why some of the reactions of glycolysis cannot be run in reverse in gluconeogenesis? 1) The last reactions occur in mitochondria and reactions there can never be reversed. 2) Glycolysis includes isomerization reactions and these can never be reversed. 3) There are some allaşteric enzymes and allosteric enzymes can never be reversed. 4) Some reactions have such large negative free energy changes that they can never be reversed under cellular conditions. Oarrow_forwardDescribe the four phases of glycolysis. What are theproducts of glycolysis?arrow_forward
- Identify the 4 steps of gluconeogenesis that are different from glycolysis. Write the reactants, enzymes, cofactors/coenzymes and products involved in the gluconeogenesis pathway.arrow_forwardGluconeogenesis is like glycolysis but in reverse. Name the 4 enzymes that are responsible for this process. What is its final product?arrow_forwardc) As what molecule does each of the monosaccharides enter glycolysis? d) How many moles of ATP are generated from the complete oxidation of one mole of lactose? Show all the steps for the calculation of moles of ATP. Be sure to account for energy used in activating the components of lactose so that they can enter glycolysis.arrow_forward
- Why is it important that gluconeogenesis is not the exactreverse of glycolysis?arrow_forwardGlycolysis and gluconeogenesis share most of their reactions and enzymes, apart from the three irreversible reactions in glycolysis. Provide a simplified schematic presentation (metabolic map) of glycolysis and gluconeogenesis; and indicate the enzymes that differ between the two processes.arrow_forwardExplain what is the relationship between glycolysis and gluconeogenesis?arrow_forward
- Identify the 4 steps of gluconeoegenesis that are different from glycoslysis. Write the reactants, enzymes, cofactors/coenzymes and products involved in the gluconeogenesis pathway. GLUCONEOGENESIS Reactant Enzymes Coenzyme/ Product Cofactorarrow_forwardWhat is the effect of an increase in the levels of glyceraldehyde-3-phosphate (G3P) on glycolysis. Make reference to at least one relevant product/byproduct of glycolysis.arrow_forwardIs glycolysis catabolic or anabolic? Discuss the importance of glycolysis.arrow_forward
