AP Glycolysis

When you click Submit (at the bottom of this web page) it will save your work on the server for me. If you get a "proxy error" hit -refresh- until you get a "Thanks"

You might want to actually write your answers in Word (so you can spell check them) and then cut-and-paste into the boxes. That way, if the computer misplaces your work you can just re-paste the answers.

Since we may work on this over more than one day, and you can work at home, I will keep track of what you have done. Feel free to click submit as you work to save your work to the server. I have however tried to keep the size of the assignment small enough that you should be able to do it in one session.

TAB OR USE THE MOUSE Between the fields....

Answer the questions as best you can. The boxes will expand as you type if you need more space. (Don't worry if it is a one word answer. The box size is standard.)

Since you will be working in groups, put all the names of the people in the group in the box. The ideal group size is 2. As an exception I will allow groups of 3. No groups of 4 or 5. If you work as a group of 3 I expect better answers. Group sizes above 3 will be penalized in the grading.

Click on the link below, and switching between this document and the open browser answer the questions. Most of the answers can be found through observation, but some require thought or research on the web.

Spend a couple of minutes “playing” at each site to figure out how it works. Some have an audio track, and I'd REALLY appreciate it if you used headphones.

Glycolysis Computer Animations

You don’t really need to go through these animations. They help you to understand a complex process. All but question 1 can be answered from the book or lecture notes.

In  go to the gizmo on energetics. As of 9/26 this is not working via student accounts on the school computers. We are working on it, but either do it from home, OR, skip it. No penalty for skipping question 1.

Question 1:  What is wrong in the first step of glycolysis?

At a much higher level go to the following sites. They all illustrate glycolysis in slightly different ways.

Do not worry/obsess about the details. 

Question 2: Glycolysis is a series of 10 reactions. A biochemical pathway. What are the initial reactants? What are the final products?

 Question 3:  Why is lactic acid fermentation VERY different from ethanol fermentation? (Think about equilibrium.)


Question 4: Why do you need to do fermentation at all? Why not just keep running glycolysis even without oxygen?


Question 5: 

Did the animations help? (I.e. should I look for animations for Krebs cycle, Oxidatitive phosphorylation etc.)
