|Many biological systems can be thought of as tiny --- but very accurate --- molecular machines that use chemical energy to do certain jobs. The above simulation shows a process that transfers energy from the right molecule (driver gear) through a polymer (rack) that runs across a pore to the left molecule. The left molecule then pushes some sort of molecule through the slider-crank mechanism.|
