effect of a string of enzymes. Adenylate cyc lase is one
instance; stim u lat ing this enzyme leads to the pro duc tion
of peri od ic-AMP, a sec ond ary mes sen ger. A series of
chem i cal reac tions then take place, chang ing the forms of
spe cif ic pro teins with in the cell, lead ing to other cel lu lar
reac tions. When the level of the pri ma ry mes sen gers falls,
the G pro tein is inac ti vat ed and its effects come to an end.
The cell uses this exceed ing ly com plex sig nal ing sys -
tem to increase the effi cien cy and speed of mes sage trans -
mis sion. The arriv al of a sin gle mes sen ger mol e cule ini ti -
ates a series of reac tions, rein forc ing the orig i nal mes sage
and trans mit ting it onward. In addi tion, the delay between
a sig nal arriv ing at a G pro tein and the cell's reac tion is
only a frac tion of a sec ond. By means of the G pro tein sys -
tem, for exam ple, light-sen si tive ret i nal cells react to a sin -
gle pho ton in just 1/100th of a sec ond. In con trast, other
cells may take up to 30 sec onds to react to exter nal sig nals.
The har mo ny between the mes sen ger and the recep tor,
and the way that their com mu ni ca tion with one anoth er
keeps us healthy at all times, are cer tain ly a great mir a cle.
Many trained chem ists and biol o gists are una ble to match
the activ i ties inside the cell, car ried out on a scale too small
to be seen with the naked eye. This under mines the claims
of coin ci dence. Indeed, Darwinists have admit ted their
help less ness in the face of the com plex sys tem in hor -
mones.
The evo lu tion ist writer Von Ditfurth express es the per -
fec tion that he observes at the cel lu lar level, with regard to
the com mu ni ca tions net work among cells:
