nucleus and the membrane, there is a
polysaccharide matrix called the cytoplasm, where organelles can be found. The
organelles are attached to a framework. The cell�s cytoskeleton.
Every living cell has the ability to detect signals from it�s
environment. The signals are usually in the form of chemical molecules, that
the cell has learned to recognize. The cell decodes these molecules into
messages, and acts upon them. The cell has a �language�. Signals and messages
are carried by particles of matter that have a very low energy requirements.
There are many, many signals rumbling around the cell. It was thought that the
cell would confuse itself in all of that background signal noise. One defense
is available to this question. The cell�s decoding mechanisms are located
downstream from the receptors. They are based on complex chemical reactions
that take place in the cell membrane and control all the responses of the cell
to the messages it receives.
Neuropeptides and ...

discoveries about the cell tell us that;

A) Each cell is not simply controlled by an accelerator and an inhibitor, and
the cell has the ability to recognize a great amount of signals. B) The number
of signals discovered in the body has increased tremendously. C) Signals within
the cell are not, as formerly believed, characteristic of an organ or function,
but they are all found in nearly all organs and are associated with nearly all
functions.

As mentioned earlier, signals are incredibly small, have low energy
requirements and weigh approximately one billionth of a gram. Scientists have
discovered new signals with the development of extremely effective chemical
methods that make ...
