proper receptors, or that have docking stations on their surfaces.

Enzymes, on the other hand, are catalysts. They arrange for chemical
reactions to be accelerated so that metabolism can take place at a useful
rate. 45
Hormones are very similar, though unlike enzymes, they do not
constantly enter into and exit from chemical reactions. In addition, hor-
mones have long-term effects on the organs they reach via the blood-
stream. For example, if you do become hungry or thirsty while reading
this book, these sensations are completely hormonal in origin.
Hormones released from specific regions of the body reach the brain
and begin setting up a sensation of hunger, making you want to eat.

(For detailed information, see Harun Yahya, The Miracle of Hormones.)
What distinguishes these two proteins, which are almost identical
in their structure and working conditions? Although they have the
same characteristics and similar geometrical shapes, proteins manufac-
tured in the body suddenly begin working as either enzymes or hor-
mones. The body has no conscious apparatus to determine that one
should act as a catalyst while the other should transmit messages. All
the other organs in the body are no different from protein and fats. It is
impossible for them to have intelligence, be able to plan and share la-
bor, identify missing components in the metabolism and to engage in
production accordingly. It is Almighty Allah Who tells the proteins pro-
duced what to do, how to behave and how to establish communica-

tions with one another. It is He Who fully knows the body He has cre-
ated, what takes place in it and the reasons behind its operations. He
determines the body's needs and how and where these will be satisfied.
He inspires each with its own task and tells each one how to behave.
Every structure in the body behaves accordingly. It is His inspirational
direction that makes enzymes different from hormones.
Allah creates whatsoever He wishes out of nothing. Our Lord has
revealed this fact in a verse:
