Once
the food is start digesting, the first nutrient that is extracted out
is glucose or sugar and released into the blood stream for energysing
the body cells calles as glucose metabolism.
What is Glucose / Carbohydrate metabolism
Digestion
and start of glucose metabolism
Once the
food we ate reaches stomach, glucose metabolism begins with first
glucose is separated and released into the blood stream and
thus glucose level in blood rises.
Insulin
secretion by pancreas
Pancreas
response to rising blood glucose level by immediately
releasing
insulin,
proportional to the level of glucose
in blood. Human Insulin is a chemical messenger (a hormone).
Glucose
consumption by body cells
Insulin in
blood comments
- liver to stop releasing glucose into
the blood-stream
- body cell to start consuming
glucose.
Glycogen
storage by the liver
After
necessary glucose consumption is completed and if there is any excess
glucose still available in the blood-stream then liver start converting
this
excess glucose in to glycogen and stored it for future requirements.
Glycogen
to glucose conversion
If we are
not having our food in time and the body
cells needs energy then liver converts back stored glycogen in to
glucose and releases it in to the blood stream.
Glucose
metabolism and diabetes
If
there is any problem or defect in the glucose metabolism; whether it is
glucose absorption, insulin secretion, glucose utilization, glucose
storage or releasing stored glucose. This minor defect in
glucose
metabolism will slowly develop
diabetes.
