With respect to digestion, we talk of two fates
The absorptive and post absorptive states.
Think of a meal as earning a wage.
You may use a bit but you’ll save some, if sage.
And the ratio is something you always must gauge.
It can certainly change as one does age.
Up to four hours after a meal
Before your insides are resting from their zeal
Insulin is governing lots of the chemistry
In your body’s energy registry.
It promotes glycogenesis, glycogen production
The storage of glucose, a major reduction.
Lipogenesis will also take place
After a meal at an increased pace.
And of course, protein synthesis also increases
As your body builds up new pieces.
But after four hours, post absorptive will dominate
And glucagon is the hormone that it will nominate.
It will cause the breakdown of things that were built
So that sources are available when you need them to the hilt.
It promotes glycogenolysis, the reverse of the above
Because now your blood glucose might need a shove.
Lipolysis, too, is also promoted
Proteolysis as well, just as devoted.
While insulin and glucagon both promote their actions
They also inhibit the other’s reactions.
