Why does a biological process that occurs without an input of energy have to increase universal entropy? - biological process of genital warts
My book says biology
"In order occur spontaneously, a process we need the entropy of the universe"
But why?
If you put two mono (or another monomer, for that matter) and a water molecule in a closed environment, you get a polymer of a species, it is an anabolic process, whereby the order of the universe.
Sorry if this is a stupid question. Any help is greatly appreciated.

When you think of the dehydration of two monosaccharides, for example, two molecules were obtained (disaccharide + water) for the two monosaccharides that are in so that it is not clear that increasing the order of the system, and I'm pretty sure that the spontaneous hydrolysis and not vice versa.
Look at it this way: a rxn is spontaneous if the Gibbs free energy dG = DH - TDS \\ \\ \\ \\ \\ \\ \\ \\ u0026lt; 0 If a process is spontaneous and DS> 0, then the entropy of the system is increased. If a process is spontaneous and DH u0026lt \\ \\ \\ \\ \\ \\ \\ \\ 0, the heat of the system will be delivered around, and dS the entropy of the environment (middle) = Q / t> 0 However, the entropy of the universe dS (system) + DS (environment)> 0
Well, this is not exactly a rigorous proof, but when dividing the world into the system and its surroundings, and reflect the change in entropy of the environment because of the heat inside or outside the system. The work of Gibbs point is that you can combine the energy and entropy in an expression of the valuable work that uMeaningful work can be extracted from the transition from one state to another, freely with less energy, and the second law places the same restriction in the useful work in a chemical system as described in a purely mechanical system.
Even if you really want a thermos, or maybe a pound of chemical thermo book this task. This topic scares most chemists and biologists of all, and not likely to find anything but gibberish on them like a parrot, who in his biology books * *. was
The increase of entropy correspond to irreversible changes in the system, since some energy must be expended as heat, what the scope of work can do a system has its limits.
