I. Energy a. Potential energy is the stored form of energy i. e.g. in chemical bonds and with concentration gradients b. Kinetic energy is the energy of movement . II. Condensation and Hydrolysis reactions a. Condensation (dehydration): aka anabolic reaction (“building up”) i. Energy is put into the system to bring “ order ” and thus decrease the value of entropy (disorder). ii. Free energy (G—amount of usable energy) is positive: energy is likely REQUIRED . b. Hydrolysis: aka catabolic reaction (“breaking down”) i. Free energy is negative (favorable): energy is likely released . ii. Disorder increases . III. Exergonic/Endergonic a. Exorgonic: energy is released (spontaneous). ΔG - b. Endergonic: energy is consumed ΔG + IV. ATP (adenosine triphosphate) a. adenine + ribose + 3 phosphate groups b. Usese energy between 2nd and 3 rd phosphate group to drive ENDERGONIC rxns. V.
