Chapter 6 Blog: An Introduction to Energy, Enzymes, and Metabolism (Michael)

Page history last edited by Michael Murphy 13 years, 6 months ago

In the first section of this page, you will write a daily summary of that day's class.  For example in  your chapter 2 blog, your first entry should be titled 9/3/10.  You should then write a one or two paragraph summary of that day's lecture, outlining the major points.  In the second section, you are required to add two items (link to a website, video, animation, student-created slide show, student-created PowerPoint presentation) and one journal article pertaining to a topic in this chapter.  A one-paragraph summary must accompany each item describing the main idea and how it applies to the lecture topic.  Please see the PBWorks help guide for assistance embedding video and other items directly in the page.  I will also produce a how-to video on using tables to wrap text around items and other useful tips.  Please see the syllabus for organization and grading details.


A.  Daily Blog


We discussed some of chapter six during class.  We talked about the laws of thermodynamic.  We also discussed energy.  We talked about potential and kinetic energy.  Kinetic energy is associated with movement and potential energy is due to structure or location.  We also talked about the equation H = G + TS.



Today in class we talked about enzymes.  We talked about how enzymes lower the activation of energy.  But enzymes do not supply energy.  Also Vmax is the velocity of reaction near maximum rate and Km is amount of substrate required to bind half the enzymes.  We also talked about competitive inhibition and non-competitive inhibition.  Competitive inhibitors bind to the active site of an enzyme an inhibits its ability.  Non-competitive inhibitors bind to the allosteric site of an enzyme and it never reaches Vmax. 



B.  Useful Materials

This is a very annoying song about the laws of thermodynamics.

This is a very simple song about kinetic and potential energy.  It gives plenty examples of each form of energy. 

The structure of Haemophilus influenzaeprephenate dehydrogenase suggests unique features of bifunctional TyrA enzymes.

This article discusses competitive inhibition of HinfPDH in TyrA proteins.

Need a bit more detail Michael for both the summaries.
