Internet Links for Exam 1

Some of these links require the MDL "Chime" plug-in.   The Windows computers in the computing labs have this plug-in linked to Internet Explorer,but they may or may not have it linked to the Netscape version on these machines.

For your own computer, you can download Chime from the MDL website if you have a suitable computer and operating system.   Get information about downloading Chime to determine which version (if any) fits your computer, browser, and operating system, and for instructions about installation.

Professor William McClure at Carnegie Mellon University has developed a couple of web pages that are a useful introduction to Chime.   Visit his Chime Demonstration of ATP and his demonstration of Chime displays of other small biological molecules.   You may also find his Chime Viewer's Guide helpful for learning to take advantage of all the features of Chime.

• The UTMB web page on lysosomes directs you to the Arkansas website for "updates", but the information on lysosmes is the same on both the UTMB page and the Arkansas website.   The ends of both presentations provide information about why peroxisomes and lysosomes are different from each other.
• The peroxisome website presents current material about peroxisomes from a number of perspectives. The perspective of greatest interest to use is the "Scientist" perspective.

• The Carnegie-Mellon University Cell biology site has a 3-Dimensional view of a membrane, with various components identified. Click on the various buttons to highlight different parts of the membrane .   (Requires the Chime plug-in.)
• The Cell Biology course at the University of Manchester Institute of Science and Technology has some lectures on-line. This is the lecture on membrane structure and properties given by Elaine Spooncer at UMIST.
You might also find the "Problems" for lecture topics interesting in the way they ask students to organize information. Goto " http://www.bi.umist.ac.uk/users/mjfssjm4/1CAT/default.htm"
• The UTMB website provides a very good presentation of many features of membrane structure and properties.   The following sections are of particular interest:
• A description of experiments demonstrating membrane fluidity.
• The presentation on freeze fracture of membranes.

Membrane Transport

• You can find interactive molecular models for several membrane channels and pumps at the Carnegie-Mellon University molecular models website.
• Professer Duane Sears at the University of California as Santa Barbara has a good demonstration of protein flexibility with his information on Hemoglobin allosteric changes.     (Requires the Chime plug-in.)

• A web page for the Human Biology course at the University of Virginia has a nice overview of the cytoplasmic pathway for sugar metabolism (Glycolysis) with an animated inset stepping thorough each reaction of the pathway while you view the pathway as a whole.
• The Human Biology course website at the University of Virginia also has a diagram of the mitochondrial electron transport chain.
• The Cell Biology course website at UTMB has a nice overview of the role of mitochondria in energy metabolism, as well as a nice electron micrograph of the ATPase "knobs" of isolated inner membranes.
