The Chemistry of Life Why are we studying chemistry? Chemistry is the foundation of Biology Proton Neutron Electron Hydrogen 1 proton 1 electron Oxygen 8 protons 8 neutrons 8 electrons + 0 ? Everything is made of matter Matter is made of atoms The World of Elements C Different kinds of atoms = elements H O N P S Na K Mg Ca Life requires ~25 chemical elements About 25 elements are essential for life Four elements make up 96% of living matter: ? carbon (C) ? hydrogen (H) ? oxygen (O) ? nitrogen (N) Four elements make up most of remaining 4%: ? phosphorus (P) ? calcium (Ca) ? sulfur (S) ? potassium (K) Effect of electrons electrons determine chemical behavior of atom depends on number of electrons in atom?s outermost shell valence shell Bonding properties

Water is Special Polarity There are two types of covalent bonds, polar and nonpolar While nonpolar molecules share electrons equally, polar molecules do not. This results in one part of the molecule being partially positive and another part being partially negative. 2 Student Misconceptions and Concerns

Chapter 3 ? Water & Fitness of the Environment Effect of Water?s Polarity Polarity of water causes hydrogen bonding Water is made up of 2 hydrogen and 1 oxygen; held together by 1 covalent bond Oxygen is slightly negative and hydrogen is slightly positive ?> polarity Polarity causes hydrogen to be attracted to other oxygen molecules, creating hydrogen bonds; each molecule can be connected to 4 other molecules 4 properties of water Water?s cohesion Stabilization of temperature Expansion upon freezing Versatility as a solvent Cohesion of water molecules Hydrogen bonds keep water molecules sticking together - hydrogen bonds are very weak; they form and reform with great frequency Cohesion: the process in which hydrogen bonds hold the substances together

Self-Quiz Questions 1) In what way do the membranes of a eukaryotic cell vary A) Phospholipids are found only in certain membranes. B) Certain proteins are unique to each membrane. C) Only certain membranes of the cell are selectively permeable. D) Only certain membranes are constructed from amphipathic molecules. E) Some membranes have hydrophobic surfaces exposed to the cytoplasm, while others have hydrophilic surfaces facing the cytoplasm. Answer: B 2) According to the fluid mosaic model of membrane structure, proteins of the membrane are mostly A) spread in a continuous layer over the inner and outer surfaces of the membrane. B) confined to the hydrophobic core of the membrane.
