Biological muscle cells can be thought of as nanometres that utilize the chemical energy of ATP to produce mechanical work. Measurements show that the active proteins within a muscle cell (such as myosin and act in) can produce a force of about 7.5 pN and displacements of 8.0 nm. How much work is done with such proteins?
