Use your models to answer the questions. 1. The summary formula for cellular respiration is     C6H12O6 6 O2 6 CO2 6 H2O Energy a. Where is each of the reactants b. Where is each of the products produced in the used in the overall process? overall process?     C6H12O6 6 O2 6 CO2 6 H2O Energy  Glycolysis Oxidative Pyruvate Oxidative ATP/glucose phosphorylation Acetyl CoA phosphorylation Glycolysis (2), and Krebs cycle Krebs (2 GTP), oxidative phosphorylation (up to 34) 2. In cellular respiration, the oxidation of glucose is carried out in a controlled series of reactions. At each step or reaction in the sequence, a small amount of the total energy is released. Some of this energy is lost as heat. The rest is converted to other forms that can be used by the cell to drive or fuel coupled endergonic reactions or to make ATP. a. What is/are the overall b. What is/are the overall c. What is/are the overall function(s) of glycolysis? function(s) of the Krebs function(s) of oxidative cycle? phosphorylation? Oxidation of glucose to Oxidation of Oxidation of NADH and 2 pyruvate. Generates 2 ATP pyruvate/acetyl CoA to FADH2to H2O (and NAD and 2 NADH per glucose. carbon dioxide. Generates or FAD). Generates H ion 2 GTP, 6 NADH, and concentration gradient and 2 FADH2 per glucose. therefore ATP. 3. Are the compounds listed here used or produced in: Glycolysis? The Krebs cycle?
