Glycolysis After viewing the animation‚ answer these questions. 1. Cells derive energy from the oxidation of nutrients‚ such as glucose . 2. The oxidation of glucose to pyruvate occurs through a series of steps called glycolysis . 3. How many carbons are in a molecule of glucose? 6 carbon glucose 4. The energy related during these oxidation reactions is used to form adenosine triphosphate ( ATP )‚ the Energy

are enzymes that can be easily extracted‚ and because peroxidases can liberate oxygen from hydrogen peroxide‚ their activity can easily be measured in the laboratory (Pitkin 1992). The rate of oxygen release is followed by measuring the rate of oxidation of guaiacol‚ which turns brown in the presence of oxygen and thus can be quantified in a spectrophotometer (Nickle 2009). We hypothesize that as we increase the temperature of reaction‚ kinetic energy will increase the frequency with which
