A Wonderful Messenger:
Nitric Oxide

like an electronic postal system, send-
ing many messages at high speed to
their destinations.
When GC enzyme in the smooth
muscle cells receives the message
brought by NO, it begins its activity.
The duty of this worker enzyme is to
turn the GTP, the energy-carrying mol-
ecules, into cGMP. The many reactions
that occur between these stages are
still unknown.
To put it in most simplest terms,
at the end of the activity of the en-
zymes, the concentration of calcium in
the muscle cell diminishes, causing a
separation in the fibers and the relax-
ing of the muscle cells. As a result of
this, the vessels dilate. In short, the The speed at which the nitric
oxide molecule delivers its mes-
message carried by the nitric oxide sage can be compared to an
molecule has a vital importance in the electronic postal system.
adjustment of the pressure in the ves-
sels, and what is explained here is only one of the millions of complex
communication operations that go on every moment in our bodies.
How is it that NO molecules that have no intelligence or conscious-
ness know the perfect systems that world-renowned professors can still
not fathom? And how is it that they know, to the last second, when they
must begin their activity and when they must end it? How is it that, as
soon as it is produced, as if it had received a command from somewhere,
it is able to deliver high-speed messages to the right address, exactly on
time and without fail?
NO cannot perform these wonderful operations by itself. This mole-
cule, like millions of other molecules in nature, is the work of a flawless cre-
ation, and it is a demonstration of God's limitless power and knowledge.
