Unformatted text preview: energy that could be used to do work Chemical reactions occur with some change in free energy (delta G) Essential Concepts Essential Concepts Spontaneous reactions have a negative delta G, release energy, increase disorder Energetically unfavorable reactions ( nonspontaneous ) have a positive delta G, absorb energy, decrease disorder they do not occur unless coupled with a spontaneous reaction Coupling occurs via high energy carrier molecules the major one is ATP A phosphate is transferred from ATP to activate an intermediate, allowing the reaction to occur ATP is used to create high energy (phosphorylated) forms of each subunit in the biosynthesis of macromolecules such as proteins and polysaccharides...
