(a)
Interpretation: To identify the number of “common” steps in the gluconeogenesis and glycolysis processes in which the reactants/products are the reverse of each other and the enzyme is same.
Concept introduction: Glycolysis
In the gluconeogenesis pathway, glucose is produced from non-carbohydrate substances. The net overall equation for gluconeogenesis is as follows:
An overview of the pathways of glycolysis and gluconeogenesis is as follows:
(b)
Interpretation: To identify the number of “common” steps in the gluconeogenesis and glycolysis processes in which the reactants/products are the reverse of each other and the enzyme is different.
Concept introduction: Glycolysis metabolic pathway is a ten-step enzyme catalyzed pathway in which a glucose molecule is converted to two pyruvate molecules. ATP and NADH-reduced coenzymes are produced along with pyruvate. The net overall equation for glycolysis is as follows:
