b) What is gluconeogenesis? Explain its significance.
ANS- Gluconeogenesis (GNG) is a metabolic pathway that results in the generation of glucose from certain non-carbohydrate carbon substrates. ... Gluconeogenesis is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms.
The synthesis of glucose from noncarbohydrate precursors is called gluconeogenesis. This metabolic pathway is very important because glucose is the primary energy source for the brain. Erythrocytes do not have mitochondria and derive all of their energy by glycolysis converting glucose into two molecules of lactate.
