Chapter 7: Useful Materials

This video gives a complete overview of glycolysis. He breaks down the process of glycolysis and explains the steps involved in this process. Glycolysis is part of cellular respiration, which also consists of two other parts called the Krebs Cycle (Citric Acid Cycle) and the electron transport chain. This video mainly focuses on glycolysis, which is the break down of glucose. He explains how there are two main stages of glycolysis; which can be called the investment phase (which uses 2 ATPs to break down glucose into two 3-carbon compounds with a phosphate attached) and the pay-off phase (when each of the phosphate attached to the carbon turns into pyruvate, which is essentially the end product of glycolysis - for every one molecule of glucose there are 2 molecules of pyruvate). I thought this video was very helpful in reviewing the process of glycolysis.

I found an animation of the Krebs Cycle (Click Here) online. It explains the Krebs Cycle and each individual step involved in this process. The Krebs Cycle begins after the two molecules of the three carbon sugar produced in glycolysis are converted to a compound called acetyl CoA. At the end of the animation there is a review, where you have to place each step of the Krebs Cycle in the correct order.
