Some molecules are unable to pass through the cell membrane on
their own because of their small size. Channel and transporter proteins
help molecules and ions to which they give permission to pass through the
membrane. The cell membrane’s proteins will transport specific substances
and behave most carefully in selecting them. For example, the sugar-trans-
porting system will not transport amino acids.
The transporter protein distinguishes between the two molecules on
the basis of their forms and the number of atoms they contain. For instance,
two molecules may have the same number of atoms and carry the same
chemical groups, but if one has the slightest variation in its molecular form,
the transportation system will refuse to carry that molecule (Figure 136).
How is it possible for a transporter or channel molecule to recognize
the chemical formula of another molecule and to distinguish it on the basis
of the number of its atoms? Could a protein devoid of intelligence and con-
sciousness of its own accord assume a responsibility that will be of benefit
to the cell? It is, of course, impossible for these proteins to engage in divi-
sion of labor of their own accord, to identify beneficial molecules, to as-
sume the job of transporting them inside the cell or to fulfill these
responsibilities to the letter as the result of sheer chance. Any rational, hon-
est person will see in these details evidence of the infinite knowledge of
Almighty God, the Creator of all things from nothing.

Figure 136.
Every transporter protein is responsible for carrying a different mol-
ecule. For example, in the event of the slightest geometrical differ-
ence in a molecule’s shape, the transportation system will detect
this and abandon the molecule, refusing to carry it.
