This incredible process takes place many billions of times in every cell of your body during your
lifetime. It is one of many such processes that must take place regularly in all living cells for life to
continue.
The process by which the protein passes from compartment to compartment in the cell has been
called “gated transport”. This is a means of allowing only certain chemicals through the wall and
keeping all the rest out.
Consider step 3 of the journey of the protein, where the signal on the DNA code copy opens the
pore and allows the code copy out of the nucleus.
We see that three elements are needed to make the system work:
- an identification tag
- a scanner
- a gate activated by the scanner
If any of these elements are not in place and working, the system will not work.
The last stage of the protein’s journey is even more complex. The process by which it ends up in
the waste disposal unit of the cell needs these elements to make it work
- an identification tag on the protein
- a scanner on the sub-compartment
- an identification tag on the sub compartment
- a scanner in the wall of the waste disposal unit
- a gate in the wall activated by the scanner
Both of these systems are what we can call “irreducibly complex”. They cannot work unless all of
the components are there.
When there is just one defect in this system that we have just looked at, the results are tragic.“I-cell disease” is caused when there is just one defect in this incredibly complex process. The
protein never reaches its correct destination – like a letter delivered to the wrong address. As a
result the cell cannot dispose of its waste products. The terrible consequences can include:
- Stunted growth
- Puffed up eyes and face
- Bent legs
- Difficult movement
- Mental retardation
- Enlarged heart, liver and spleen
- Probable death by the age of 5
This shows just how vital it is to have all of theses complex systems in perfect working order before
the cell can work.
No one has offered a plausible explanation of how these systems could have developed as required
by evolution. A search of the professional biochemical literature shows that no one has ever
proposed a detailed route by which these systems could have evolved.
Talking about the membranes which surround the different parts of the cell (called “organelles”), the
famous Turkish evolutionist Professor Ali Demirsoy wrote in his book Inheritance and Evolution:
One of the most difficult stages to be explained in evolution is to scientifically
explain how organelles … developed from these primitive creatures … no creature
or group has yet been found with organelles of a simpler construction in any way, or
which are more primitive. In other words, the organelles carried forward have
developed just as they are. They have no simple and primitive forms.
There are theories which attempt to explain how the cell evolved. Virtually all of them assume that
the cell came from simpler organisms already having all the complex systems that cells we know
today have. These theories do not explain the evolution of the incredibly complex sub-cellular
systems that we have been looking at.
As we saw earlier, we must remember not to confuse facts and opinions.
The facts are:
- The cell which is the basis of all life is incredibly complicated
- The cell contains many “irreducibly complex” systems
- Tragic results occur if just one element in one of the many complex systems does
not work correctly
- No one has ever discovered a partially developed cell
The many “irreducibly complex” systems in the cell, which is the basis of all life,
point to a designer and creator. |
