Life's Engines: How Microbes Made Earth Habitable (Science Essentials): 24

Product Information

Experiments undertaken so far have studied single proteins that are plucked out of the cell and fed ATP molecules “by hand” to give them energy. In 2002 Carlos Bustamante at the University of California and co-workers stretched a single RNA molecule by using a laser trap to tug at a tiny plastic bead attached to one end. Movers rotate randomly when they change direction, and their rotation is not necessarily the same as their movement direction, ie, they aren't always facing the direction they are moving.

Above all, it’s safe and pleasant for passengers too – a real win for a vehicle that has no purpose beyond being the ultimate family car. Its laws of energy and entropy gave scientists a way to describe the interplay of energy and matter.Recent studies have aimed to try to find the relation between Gibb’s free energy and the microbial growth of microorganisms, highlighting the importance of thermodynamics in life. As Life was not able to build a car on its own, the team purchased the still-born Formula One chassis from First Racing that had been designed by Richard Divila for Lamberto Leoni´s abortive Formula One team the year before.

Yet even ignoring for a moment the subtle differences between the macro- and micro-scales, and between the definitions of equilibrium and non-equilibrium, there is one final limitation of 19th-century thermodynamics that is potentially even more significant. In the early 1800s there was little grasp of the rules of energy, or of the nature of heat and temperature. Kelvin, who died 100years ago on 17December1907, became professor of natural philosophy at Glasgow University at the age of 22, and went on to become a quintessential grandee of Victorian science, ennobled peer and holder of a fistful of innovative patents (see “Kelvin: the man behind the title”).Gibb’s free energy emerges as a critical player, determining the spontaneity of these chemical reactions.
