Clutch Enables Your Motors to Achieve 100% Efficiency 02/23/2005 Those little ATP synthase motors (see 01/30/2005 entry) in your body and (in all living cells) made news again in Nature1 last week. Scientists in Tokyo performed an ingenious set of experiments to measure the efficiency of the F1 synthesizing domain. They attached a tiny magnet to the camshaft so that they could turn it with electromagnets at will, and they carefully measured the amount of ATP synthesized or hydrolyzed as the motor turned anticlockwise or clockwise under their control. In the hydrolysis cycle, they found that the motor...
