I have a question on glucose here!

[Keall]

i'm having problem in answering this question.. seems like i don't know which answer is correct..help me please..anyone...

"After having a physical exercise,the level of glucose drop.How does the body regulate the glucose at normal rate?"

That was the question..please free me from this confusion...help..

If your blood sugar is low, you eat more sugar and it goes back up!

But if you don't have food available...I guess you die.

You need to know where, absent food, your body stores and then releases glucose from.

when glucose level is less in the blood, glucogen is converted to glucose in liver by a pancreatic harmone called glucagon

[Darby]

Well, not quite - glycogen is converted in response to glucagon. The glucagon doesn't do it directly.

[himmel]

ok can I have an answer here ?

listen buddy,
when ur blood glucose level rises up , ur pancreas will secrets protein hromone called insulin which make ur extra glucose enter ur cells and by that way, ur glucose level will return to its normal level

ready for any question

Good luck

glucagon will affect the phosphylation of glycogen through glycogen phosphorylase, thus releasing glucose-1P. This G1P then converted into G6P and enter glycolysis (if the molecule isn't transported via bloodstream); but if it's used to be transported to another tissue (ex maintaining the normal blood glucose), the G1P will be excised at the phosphate group by G1P phosphatase to yield glucose and then release to the bloodstream.

[MrMistery]

i think the same phosphoisomerase will first convert G1P to G6P and then the almighty glucose 6-phosphatase will cut the phosphate, yielding free glucose.
Also, glucagon doesn't trigger glycogenolysis in muscle, only in the liver. therefore the most important is the pathway that yields free glucose, that is exported.

[xushuhan]

When blood glucose is low, the islets of Langerhans in the pancreas, are stimulated to secrete glucagon. Glucagon will stimulate the live to convert some of the stored glycogen back into glucose. The glucose concentration will go back to the normal.
