Concept explainers
To trace: The pathway of each precursor through gluconeogenesis.
Introduction:
For the brain and nervous system of humans, blood glucose is the major fuel. However, the supply of glucose from these stores is not always sufficient such as during vigorous exercises or during fasting. For these times organisms obtain glucose from noncarbohydrate source by the pathway of gluconeogenesis.
To indicate: The location of 14C in all intermediates and in the product.
Introduction:
Gluconeogenesis is the pathway that provides glucose to cell from noncarbohydrate source. In this pathway pyruvate and other three or four carbon compounds are converted into glucose. Gluconeogenesis occurs in plants, animals, microorganisms, and
