1. Go to Dr. John Maber's website http://www.jonmaber.demon.co.uk
There is a link on our webpage titled "Glycolysis Assignment Resource".
2. There are four activities. Do them in the order I suggest.
I Review "Monosaccharide Browser"
You have done this section previously in class. Review the structure of D-glucose (aka dextrose), L-glucose, D-galactose, d-fructose,
and d-glyceraldehyde if you need a refresher.
II Read and view the activities in INTRODUCTION TO GLYCOLYSIS.
a. What is the overall reaction of glycolysis? In most textbooks it ends with pyruvate, unlike Dr. Maber's site. We will assume that it ends with pyruvate, as does our textbook.
b. What are the two key functions of glycolysis?
c. Explain why the rearrangement of atoms during glycolysis results in more energy available to do work.
d. What are the reasons for phosphorylation?
III Now, using "STEP-BY-STEP GLYCOLYSIS", learn the steps in glycolysis.
You do not need to learn the names of the enzymes, but you should be able to identify the type of reaction, such as "phosphorylation", "aldose clevage", etc. If you are hazy about what any of these terms mean, you may need to review the earlier course material.
Be prepared for a quiz on the specific reactions.
IV Now, test yourself by doing the activity titled"DESIGN IT YOURSELF GLYCOLYSIS". Try to give the correct answer before you view the next reaction. If you make an error, try to see why you made the mistake. That's how you learn!
