Carbohydrate Biosynthesis in Plants * FIGURE 20-33 ..
Gluconeogenesis is a process of biosynthesis of glucose from simpler non carbohydrate precursors such as oxaloacetate or pyruvate. It is a universal pathway in animals, plants, microbes and fungi. It converts pyruvate to glucose (reverse of glycolysis). The irreversible steps of glycolysis are circumvented by four key enzymes of gluconeogenesis. They are pyruvate carboxylase, phosphoenol pyruvate carboxy kinase, fructose-1, 6-bisphosphatase and glucose-6-phosphatase.

Chapter 19 : Carbohydrate Biosynthesis
Pentose phosphate pathway (PPP) is a secondary pathway of glucose metabolism, primary being glycolysis. Glucose enters PPP as glucose 6-phosphate. It occurs in the cytosol of tissues active in fatty acid biosynthesis. Those tissues are liver, mammary and adrenal glands and adipose tissue. There are two phases in the pathway: oxidative and non-oxidative. Glyoxylate cycle is a variant of TCA cycle and occurs in bacteria and plants. Gluconeogenesis is a process of biosynthesis of glucose from simpler non carbohydrate precursors such as oxaloacetate or pyruvate. Glucose is stored in the body in the form of glycogen. Glycogen synthesis takes place in the liver and muscle. Starch and sucrose are synthesized in plants. Lactose is synthesized in lactating mammary glands of animals.
