Tiny motors in our cells
But did you know each one
of us has billions of motors
that are much more complex
than anyone can build—in
our cells? The world’s smallest
motor is called ATP synthase
(left), and you have trillions of
them in your body. 100,000
would fit side-by-side on a millimetre.
It is very important that these motors work
correctly, because they make the fuel that our cells
run on. They produce a chemical called ATP—about
your body weight in ATP every day! Cyanide is such
a deadly poison because it stops ATP production.
This motor is powered by an electrical current,
thanks to another part of the cell that acts like a
tiny battery. It spins at 10,000 rpm, and each turn
produces three molecules of ATP. The ATP motor
is almost 100% efficient: almost all the electrical
energy is turned into ATP.
ATP synthase could not have evolved, because
you can’t have evolution before you have a living
thing that can make copies of itself, and every
example of a living thing we know of has ATP
synthase—it’s needed to live.

Another example of amazing ‘God-tech’ is
called the kinesin motor. Your body makes all
sorts of proteins that your cells need to work
correctly—but then those proteins need to get to
the correct destinations. That’s where the kinesin
motor comes in. Kinesin is a ‘walking molecule’ that
takes the proteins to the right place in the cell along
tiny ‘roadways’—thanks to address labels! It takes
125,000 ‘steps’ to move one millimetre, and it moves
100 steps every second.
