The Sugar Factory
in our Bodies
If you ate food containing a little more sugar that
you needed, a system in your body would go into action
to prevent the elevation of the proportion of sugar
in your blood.
1. First, the pancreas cells would
find and distinguish the sugar molecules from among
all the millions of other molecules in your blood. Moreover,
they would count the sugar molecules to decide if the
number were too high or too low. Amazingly, cells too
small for the eye to see, without eyes, hands, or a
brain know the correct proportion of sugar molecules
in a fluid.
2. If the pancreas cells determine
that there is more sugar in the blood than required,
they decide to store the excess. But they themselves
do not do the storing; they have other cells, located
far away, to do this job.
3. These distant cells, unless a command
to the contrary comes to them, have no desire to store
sugar. But the pancreas cells send a hormone to these
cells commanding them to store sugar. The formula of
this hormone, called insulin, has been coded in the
DNA of the pancreas cells from the moment they come
into being.
4. Special enzymes in the pancreas
cells (worker proteins) read this formula and produce
insulin accordingly. In this production hundreds of
individual enzymes perform a different function.
5. The insulin produced reaches the
target cell by the most reliable and rapid communications
network-the bloodstream.
6. The various cells that read the
command to store sugar written in the insulin hormone
obeys it unconditionally. As a result, the doors that
permit sugar molecules to enter the cells are opened.
7. But these doors do not open randomly.
The reservoir molecules distinguish sugar molecules
from among all the hundreds of other molecule types
in the blood; they intercept them and lock them inside
themselves.
8. The cells always obey the commands
sent to them. They do not misunderstand this command
and try to intercept the wrong material, or to store
more sugar than is necessary. They work with great discipline
and effort.
When you drink some tea with too much sugar, this remarkable
system goes into action and stores the excess sugar
in your body. If this system did not function, the level
of sugar in your blood would rapidly increase and you
could eventually go into a coma. This wonderful system
can even work in reverse when necessary. If the level
of sugar in the blood falls below normal, the pancreas
cells produce a different hormone called glucagon. Glucagon
sends a command to those cells that were storing sugar
and causes them to release it to be mixed with the blood.
The cells that obey this command release the sugar they
had stored.
In the intestines, carbohydrates
become glucose and are assimilated into the blood.
If the level of glucose rises too high, the pancreas
secretes a hormone called insulin which helps
the cells to absorb glucose.
The hormone unites
with the receptor that activates the glucose transporter.
The glucose enters the cell and is converted into
energy. The level of glucose in the blood remains
stable. In the case of diabetes, insulin does
not bond with the receptor and the transporter
becomes inactive. Glucose circulates in the blood
and raises its level of sugar. |
How can it be that cells without a brain, nervous system,
eyes or ears can manage to make such a complex calculation
and carry out their function perfectly? How can these
unconscious cells formed by the coming together of proteins
and fat molecules do things too complicated for humans
to achieve? What is the source of this remarkable awareness
demonstrated by these unconscious molecules? Surely
all of these delicate operations taking place in our
bodies show us the existence and power of God Who rules
over the universe and all living things.
