teins that reg u late entry to the cell behave like gate ways
and that they recog nize the sub stan ces nec es sa ry for the
cell to grow. Furthermore, it has been estab lished that
these gate ways—after per mit ting sub stan ces to enter the
cell and pre vent ing unnec es sary, harm ful mate ri als from

pub lished in the May 23 1997 issue of Science, reveal that
these entrance por tals recog nize sub stan ces that the cell
needs for growth. They active ly open to allow their
entrance, and then close. In this way, cells obtain the mol -

2- Channel in closed position.

1- Channel in neutral position. 3- Channel in open position.
The cell membrane channel in a neutral position (1) is polarized because of a change in
the electric current around the membrane (2). This later opens in such a way as to per-
mit ions to pass through the channel (3). Movement of ions along the channel is of great
importance for the survival of the cell and for it to perform its functions.
