Concept explainers
Interpretation: To identify the form of fructose that enters the glycolysis
Concept introduction: In the glycolysis metabolic pathway, a glucose molecule is converted into two pyruvate molecules. Two ATP molecules and NADH coenzymes are formed along with pyruvate.
An intermediate is defined as the transient species that is formed from the reactants in the preceding step and gets consumed in the subsequent steps to generate the products. An intermediate is formed within a multi-step reaction mechanism.
In the phosphorylation reaction, the molecule is attached to the phosphoryl group. The transfer of a phosphoryl group
In the isomerization reaction, a molecule transformed itself to another molecule, having the same number of atoms with a different arrangement.
In the cleavage reaction, the covalent bond in the large molecule is cleaved and the molecule is dissociated into two or more fragments.

- Why is glycolysis more rapid after the infusion of fructose?arrow_forwardFructose can enter glycolysis by hexokinase. If fructose is used for glycolysis what enzyme can be skipped in glycolysis? And why can this enzyme be skipped if fructose is used for glycolysis?arrow_forwardOf the 36 molecules of ATP produced by the complete metabolism of glucose, how many are produced directly in glycolysis alone, that is, before the common pathway?arrow_forward
- How many steps in gluconeogenesis are not the exact reversal of the steps in glycolysis? What kind of conversion of substrate to product does each involve? What is the common theme in each of these reactions?arrow_forwardThe hydrolysis of some disaccharides produces glucose molecules that directly enter glycolysis. What happens to other monosaccharides?arrow_forwardHow many enyzymatic reactions are there in glycolysis pathway?arrow_forward
- What is the cost (in ATP equivalents) of transforming glucose to pyruvate via glycolysis and back again to glucose via gluconeogenesis?arrow_forwardWhich reactions of glycolysis can be reversed? Which are irreversible? What is the significance of the metabolically irreversible reactions?arrow_forwardWhat happens to the electrons removed during the oxidation of triose phosphates during glycolysis?arrow_forward
- Describe the four phases of glycolysis. What are theproducts of glycolysis?arrow_forwardHow many molecules of Pyruvate can form from Glycerol metabolism as a by-product of fatty acid metabolism ? Explainarrow_forwardWhat glycolytic intermediate is fructose converted to in the muscle, such that it can be utilized in glycolysis? Glucose 6-phosphate Fructose 6-phosphate Glyceraldehyde 3-phosphate Dihydroxyacetone phosphatearrow_forward
