Final answer:
Gluconeogenesis is an anabolic process involving the synthesis of glucose from non-carbohydrate sources to maintain necessary blood glucose levels, especially when carbohydrate intake is low or in periods of fasting.
c is correct
Step-by-step explanation:
Gluconeogenesis is a form of anabolism. It is the synthesis of glucose from non-carbohydrate sources such as pyruvate, lactate, glycerol, alanine, or glutamate, and primarily takes place in the liver. This metabolic pathway is activated during periods of fasting, starvation, or low carbohydrate intake to maintain blood glucose levels. Anabolic pathways are biosynthetic; they build complex molecules from simpler ones, which is the opposite of catabolic reactions that break down molecules for energy.
An example of a catabolic process is glycolysis, where glucose is broken down to yield energy. In contrast, gluconeogenesis is anabolic because it involves the creation of new glucose molecules, necessary to provide energy for essential organs, particularly the brain, which requires glucose as its primary energy source.
