Chapter 2 Chemical Basis of Life Molecular model of a Phospholipid PowerPoint Presentation to accompany  Hole’s Human Anatomy and Physiology,  10 th  edition ,  edited   by S.C. Wache for Biol2064.01
You are responsible for the following figures and tables : Tab. 2.1 - important definitions.   Tab. 2.3 - the first ten elements of the periodic table of elements, TB, p. 969. Fig. 2.3 - Learn how to distribute proteons and electrons Fig. 2.4 - learn how to distribute protons and electrons  Fig. 2.8 - hydrogen bonds; example H 2 O. Fig. 2.6 - examples of structural and molecular formulas Read TB, p.44, on chemical reactions. Define 'isotope'. Tb, p.39.  See Clin. Appl. 2.1, TB, p. 41.   W hat is  131  I  used for ?  Tab. 2.4, 2.5; Fig. 2.10 - Study  pH, bases and acids. Tab. 2.6:  small inorganic molecules like water and carbon dioxide  Tab. 2.8 – Macromolecules.  Fig. 2.11 and 2.12;  Fig. 2.15 and 2.16;  Fig. 2.17 and 2.18 - note the formation of the covalent bond;  Fig. 2.21.
