Figure 2.1 Differences between man-made and
biological machines. (a) Biological molecules
assemble to form molecular machines that play
essential roles such as cell signaling, motion, and
DNA duplication. (b) The input energy level of
biological machines is not far above average
thermal energy and thus their operations are
slow and ambiguous. On the other hand,
man-made machines are operated at energies
much higher than average thermal energy and
operate rapidly and accurately.
