The Miracle in the Cell Membrane
chan nels open only when they recog nize the appro pri ate
ions. However, every open ing and clos ing in the cell
mem brane takes place in a few mil lionths of a sec ond—
an excep tion al ly brief space of time. Were it any longer,
then all your bod i ly func tions would slow down, and
you would be late in per ceiv ing our sur round ings and in
react ing to those per cep tions. With that decel er at ed
mode of life, it would be impos si ble for the cells—and
there fore, for you—to sur vive. In that regard, the speed
at which your sys tems func tion is just as impor tant as
those sys tems them selves. If entry and depar ture
through just one cell mem brane was slow er than it
should be, then the order in your body would be dis rupt -
ed. Therefore, every detail in your body rep re sents a ref -
u ta tion of the the o ry of evo lu tion's claims of grad u al
devel op ment.

The above diagram shows the closed voltage ion channels in the cell membrane. (A)
Normally the closed voltage sodium channel is closed. (B) When the electrical cur-
rent reaches a specific level, the voltage gate is opened and sodium is permitted to
enter the cell. After a certain time, the gates are again neutralized and the channels
are closed.
