Gluconeogenesis

Gluconeogenesis

Gluconeogenesis. What is the Gluconeogenesis ?. Gluconeogenesis is making a new glucose from non-carbohydrate precursors In other words: Create new glucose from the products of its breakdown Its main function is to supply blood glucose in cases of carbohydrate deficiency

Glycolysis

Glycolysis

Glycolysis. Glycolysis takes place in the cytosol of cells. Glucose enters the Glycolysis pathway by conversion to glucose-6-phosphate . Initially there is energy input corresponding to cleavage of two ~P bonds of ATP. 1. Hexokinase catalyzes: Glucose + ATP ? glucose-6-P + ADP

The pentose phosphate pathway

The pentose phosphate pathway

The pentose phosphate pathway. Important for both biosynthesis and catabolism Can operate at the same time as glycolysis Can operate aerobically or anaerobically. The pentose phosphate pathway. Begins with oxidation of glucose-6-phosphate to 6-phosphogluconate
