Bisphosphatase
WebFructose 2,6-bisphosphate, present at high concentration when glucose is abundant, normally inhibits gluconeogenesis by blocking fructose 1,6 bisphosphatase. In this genetic disorder, the phosphatase is active irrespective of glucose level. Hence, substrate cycling is … WebSedoheptulose-1,7-bisphosphatase (SBPase; EC 3.1.3.37) catalyses the dephosphorylation of sedoheptulose-1,7-bisphosphate in the regenerative phase of the Calvin cycle, Antisense plants with reduced levels of SBPase have decreased photosynthetic capacity and altered carbohydrate status, leading to modifications in …

Identify all the true statements. In the liver, stimulation of the glucagon receptor leads to activation of fructose 1,6-bisphosphatase (FBPase-1) activation of PKA (cAMP-dependent protein kinase) activation of insulin receptor kinase conversion of ATP to cAMP activation of phosphofructokinase-2 (PFK-2) activation of glycogen ...
WebFructose 2,6-bisphosphate is a regulator of both glycolysis and gluconeogenesis for the phosphofructokinase reaction of glycolysis and the fructose 1,6-bisphosphatase reaction of gluconeogenesis. In turn, the concentration of fructose 2,6-bisphosphate is regulated by many hormones, second messengers, and enzymes.
WebReaction II is catalyzed by an allosteric enzyme that is inhibited by fructose-2-6-bisphosphate. Which of the following is correct concerning the metabolic reaction shown below?Pyruvate + CO2 + ATP → oxaloacetate + ADP + Pi The enzyme that catalyzes this reaction is activated by high concentrations of acetyl-CoA. Students also viewed WebThe meaning of BISPHOSPHATE is a compound containing two phosphate groups.
Webdefect in the liver enzyme fructose l,6-bisphosphatase results in abnormally high levels of lactate in the blood plasma. Explain. In the liver, lactate is converted to pyruvate and then to glucose by gluconeogenesis. This pathway includes the glycolytic bypass step catalyzed by fructose 1,6-bisphosphatase.
