Unformatted text preview: Quantity of energy doesn't change. Quality does. H = G + TS where H = Total Energy, G = Free Energy (usable energy), T = Temperature, S = Entropy For a spontaneous process: G(final) - G (initial) = dG = negative (meaning spontaneous) Exergonic: release energy (eg. digest glucose) Endergonic: sucks up energy (eg. photosynthesis) TAKE HOME MESSAGE #2: Reactions run downhill; they will occur spontaneously if the end products have less free energy than the starting products. Q: How can a cell get endergonic reactions to occur? A: employ a temporary storage of energy...
