After protein is produced, dense traffic continues within the cell. Protein is either re-
leased from the cell by special transporters, carried to the place in the body where it
will be used, or left in the golgi apparatus to be stored and packed until it is needed.
This is the reason for the constant protein traffic within the cell.

born human being for a newly produced protein. Let us give some written
and spoken advice to a new baby born in an imaginary city with a billion
inhabitants as to where it can find food and clothing, how it can find what
it needs, and where it can find a job. Certainly a baby does not know the
environment in which it was born; it would not be possible for it to find by

itself any place in such a remarkably crowded city. In order for it to find its
way without getting lost, it would be necessary for this person to spend
years in this city, getting to know it. In order for a person to achieve such a
thing he would need a long time; it is certainly surprising, then, that a pro-
tein without intelligence or consciousness can do this perfectly.
The secret of how proteins can overcome the obstacles they encoun-
ter and find the right address is hidden in the expert design of the cells.

Latest research in the science of cells has revealed some wonderful mech-
anisms in the micro-world of cells.
