Document Summary

Anabolism: 2 or more (atoms, ions, or molecules) combine to form a bigger molecule, energy is required to build larger molecules. Synthesis reactions: two or more small molecules combine to form a larger molecule. Catabolism: chemical bonds broken, 2 or more (atoms, ions, or molecules) are disassociated, energy is given off or released, example- digestion. Exchange or displacement reactions: combination of catabolism and anabolism, molecules exchange positions. Lass of mass action: direction determined by amount of substance, example- ph balance, ab + cd abcd ac + bd. Oxidation: molecule loses electrons, called an electron donor or reducing agent, often in the form of hydrogen atoms. Reduction: molecule gains electrons, reduced molecule called electron acceptor. In cells: oxidation and reduction reactions are coupled, substance 1 is oxidized while substance 2 is reduced, oxidation gives off or produced energy, cell oxidizes glucose to produce energy for (cid:272)ell"s work. Hydrogen bonds: weak bond no sharing of electrons, attractions between polar molecules, physiological importance.
