Fructose 1,6-bisphosphate aldolase is another temperature dependent enzyme that plays an important role in the regulation of glycolysis and gluconeogenesis during hibernation. [14] Its main role is in glycolysis instead of gluconeogenesis, but its substrate is the same as FBPase's, so its activity affects that of FBPase in gluconeogenesis.
Glucose-6-phosphate can then progress through glycolysis. [1] Glycolysis only requires the input of one molecule of ATP when the glucose originates in glycogen. [1] Alternatively, glucose-6-phosphate can be converted back into glucose in the liver and the kidneys, allowing it to raise blood glucose levels if necessary. [2]

Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...
Finally, the cell will increase the rate of glycolysis within itself to break glucose in the cell into other components for tissue growth purposes. An example of positive feedback mechanism in the insulin transduction pathway is the activation of some enzymes that inhibit other enzymes from slowing or stopping the insulin transduction pathway ...
Glucose transporters are classified into three groups based on sequence similarity, with a total of 14 members.All GLUT proteins share a common structure: 12 transmembrane segments, a single N-linked glycosylation site, a large central cytoplasmic linker, and both N- and C-termini located in the cytoplasm.

Diabetes mellitus type 1 is caused by insufficient or non-existent production of insulin, while type 2 is primarily due to a decreased response to insulin in the tissues of the body (insulin resistance). Both types of diabetes, if untreated, result in too much glucose remaining in the blood (hyperglycemia) and many
This amplifies the effect of activating glycogen phosphorylase. This inhibition is achieved by a similar mechanism, as protein kinase A acts to phosphorylate the enzyme, which lowers activity. This is known as co-ordinate reciprocal control. Refer to glycolysis for further information of the regulation of glycogenesis.
