Document Summary
>>>>>the chemistry of life is organized into metabolic pathways. >>>>>energy transfers are subject to the laws of thermodynamics (see fig 8. 3) --first law of thermodynamics energy can be transferred and transformed, but it cannot be destroyed (i. e. , the energy of the universe is constant) --second law of thermodynamics every energy transfer or transformation makes the universe more disordered (i. e. , every process increases entropy) --entropy (s) the quantitative measure of disorder that is proportional to randomness. Thermodynamics can determine whether or not a chemical reaction will occur in the cell, and how much energy it will consume or release. >>>>>free energy and spontaneous reactions (see fig 8. 5) --free energy (g) the portion of energy available to do work; it"s the difference between the total energy (enthalpy) and the energy not available to do work (ts) --total energy (h) or enthalpy (h) is the total energy of a system.
