diabetes/insulin - (Nov/03/2007 )
Hi there,
When say you have a meal and glucose enters the beta cells and etc etc insulin is released...well does it bind to insulin receptors on other tissues to uptake glucose?...I just want to know...is there only a bit of glucose that enters via the B-cells only to let the pancreas release insulin while the majority of the insulin is taken up my other cells ie muslce?

only little amounts of glucose enter the ß cells of the pankreas.
think of it like the probe of a pH meter that changes the pH a little.
you are right insulin is spread in the whole body and the other cells take up the glucose.
it has different effects on different cell types though.
liver and muscle cells take up the most.

low amounts of insulin are already released by anticipating a meal, and even if you do not take up carbohydrates but other food; higher amounts of insulin are, of course, released after taking up glucose-providing carbohydrates
