Reading

Wed. 1 Sep.
Course Syllabus and Organization . Introduction to the Cell . Prokaryotes and Eukaryotes. Unicellular and Multicellular Life. Lecture Notes

Optional Web Resource: Cells Alive! A large collection of light micrographs showing a wide variety of cells and featuring time-lapse photography. Includes many video clips and animations.
Ch. 1
Ch. 7 (pp. 102-107)

Fri. 3 Sep.

Note: Monday labs meet today!
Chemicals in the Cell I. Elemental composition. Atoms & isotopes. Strong and weak chemical bonds. Covalent bonds and organic molecules. Ionic and Hydrogen bonds. Polar and non-polar molecules. Lecture Notes

Optional Web Resource: The Periodic Table: a web periodic table, with information and links to data about the biological significance of each element. Click on an element to explore its properties.

Ch. 2

Mon.6 Sep.
Labor Day Holiday -- no classes today

Wed. 8 Sep.
Chemicals in the Cell II. Types of chemical reactions. The importance of weak interactions in biological systems. Roles of water, acids, bases, and buffers. Important functional groups. Lecture Notes
Required Web Activity: Building Molecules: An interactive study guide from The Biology Place. Password access required -- this came with your new text, or can be purchased by credit card or check from The Biology Place.

Optional Web Resource: Properties of Water: each image is a link allowing you to view enlarged graphics or short movies (you will need some type of mpg file viewer to see the movie. Browsers in university labs should be configured for this. Your browser will suggest possible links if you don't have a configured movie viewer.)

Ch. 3

Fri. 10 Sep.
Chemicals in the Cell II (cont.) . Important functional groups. Macromolecules & monomers. Isomers. Lecture Notes -- see Wed. Sep. 8 Ch. 4

Mon. 13 Sep.

Biomolecules: Lipids. Lecture Notes on Lipids

Required Web Activity: Properties of Biomolecules: An interactive study guide from The Biology Place.
Optional Web Resource: Monosaccharide Browser: a Web source of information about sugars. Suggested starting point: D-Glucose. Play with the button options to see various changes to the sugar. Note what happens when you convert from "aldose" form (-C=O group at the terminal position) to "ketose" form (-C=O group in an internal position), and note that you have now changed the name of the sugar, since it is a different isomer. Try clicking "Reverse All" to produce a mirror image (enantiomer) of the sugar, shown by changing L-forms into D-forms. what happens when you push "Delete C-2"?
Ch. 5

Wed. 15 Sep.

Biomolecules. Carbohydrates. Proteins.
Lecture Notes on Carbohydrates
Lecture Notes on Amino Acids and Proteins
Note: DNA and RNA will be postponed until after cell structure. These topics will not be covered on exam #1.
Required Web Activity: Properties of Biomolecules: An interactive study guide from The Biology Place.

Optional Web Resource: Jack Brown's molecular images: images of proteins and DNA in various representations. Takes a while to load, but worth browsing.
Ch. 5

Fri. 17 Sep.
Mon. 20 Sep. Energy transformations & enzymes. Metabolism. Thermodynamics, chemical equilibrium, and free energy. Reaction rates and activation energy. Enzymes as 3D stereospecific catalysts. Lecture Notes on Enzymes
Optional Web Resource: Energy, Enzymes, and Catalysis Problem Set from the University of Arizona. Answer the questions correctly and you sail right through. Choose a wrong answer and get a quick one-page tutorial on information you need to review. A nice way to see how well you understand these issues.
Ch. 6

Mon. 20 Sep.

Required Web Activity: Cell Structure and Function: An interactive study guide from The Biology Place.

Optional Web Resource: The Virtual Cell. Select an action from the list on the right (e.g. cut, view EM), then click on the image of the cell to see the result of your action. This is a good way to explore features of the cell.
