exergonic in a sentence

Examples

1. At high temperatures, the forward reaction is therefore endergonic, favoring the ( exergonic ) reverse reaction toward CO, even though the forward reaction is still exothermic.
2. Of course, in all cases the net reaction of the " total " system ( the reaction under study plus the puller or pusher reaction ) is exergonic.
3. According to the Marcus formula the rates increase also when the reactions are more exergonic, however only as long as & Delta; G 0 is positive or slightly negative.
4. Subsequent hydrolysis of the product PP i ( by the enzyme inorganic pyrophosphatase ) is highly exergonic, and this reaction makes the formation of acyl-CoA spontaneous and irreversible.
5. All physical and chemical systems in the universe follow the second law of thermodynamics and proceed in a downhill, i . e ., " exergonic ", direction.
6. A reaction will be a spontaneous process at a certain temperature if the products have a lower Gibbs free energy ( an exergonic reaction ) even if the enthalpy of the products is higher.
7. Endergonic reactions can be achieved if they are either " pulled " or " pushed " by an exergonic ( stability increasing, negative change in free energy ) process.
8. My favorite example is dissolving ammonium nitrate in a small amount of water, which is exergonic ( so it occurs spontaneously ) but very endothermic ( you can use it to freeze water ).
9. This process is highly exergonic ( accounting for approximately a  " 19kJ change in free energy ), and therefore greatly increases the energetic favorability of reaction system when coupled with a typically less-favorable reaction.
10. This exergonic fall in potential energy along the way is used to draw ( not pump ! ) H + ions from the lumen of the thylakoid into the cytosol of a cyanobacterium or the stroma of a chloroplast.
