Document Content and Description Below

ESSENTIAL CELL BIOLOGY, FOURTH EDITION CHAPTER 13: HOW CELLS OBTAIN ENERGY FROM FOOD © 2014 GARLAND SCIENCE PUBLISHING The Breakdown and Utilization of Sugars and Fats 13-1 Provide a brief descri ... ption of the process by which the body derives energy from food. Include in your description the three stages of catalysis, and delineate the input and output that connect each stage. 13-2 Glycolysis is an anaerobic process used to catabolize glucose. What does it mean for this process to be anaerobic? (a) no oxygen is required (b) no oxidation occurs (c) it takes place in the lysosome (d) glucose is broken down by the addition of electrons 13-3 Which of the following stages in the breakdown of the piece of toast you had for breakfast generates the most ATP? (a) the digestion of starch to glucose (b) glycolysis (c) the citric acid cycle (d) oxidative phosphorylation 13-4 The advantage to the cell of the gradual oxidation of glucose during cellular respiration compared with its combustion to CO2 and H2O in a single step is that ________________. (a) more free energy is released for a given amount of glucose oxidized. (b) no energy is lost as heat. (c) energy can be extracted in usable amounts. (d) more CO2 is produced for a given amount of glucose oxidized. 13-5 Indicate whether the following statements are true or false. If a statement is false, explain why it is false. A. CO2 and H2O are generated during the oxidation of food molecules. B. Activated carrier molecules store heat energy for the cell to use later. C. Catabolism is a general term that refers to the processes by which large molecules are synthesized from smaller molecules. D. The oxidation of sugar is an energetically favorable process [Show More]
