 Question 1
2 out of 2 points | | | Which part of cellular respiration takes place in the cytosol?Answer | | | | | Selected Answer: | glycolysis | | | | |
 Question 2
2 out of 2 points | | | An aerobic pathway requires _______.Answer | | | | | Selected Answer: | oxygen | | | | |
 Question 3
2 out of 2 points | | | Which of the following is NOT an end product of aerobic cellular respiration?Answer | | | | | Selected Answer: | oxygen gas | | | | |
 Question 4
0 out of 2 points | | | In the first few steps of glycolysis, two ATP molecules are actually consumed instead of produced. Why must energy be added to the glucose molecule first before the ultimate harvest of 36 ATP molecules can be attained?Answer | | | | | Selected Answer: | Glucose contains too much energy for the cell to use. To compensate for the overabundance of ATP produced by glucose metabolism, some ATP has to be wasted at the beginning of the process. | | | | |
 Question 5
0 out of 2 points | | | The final result of ATP production after anaerobic respiration is ________.Answer | | | | | Selected Answer: | high relative to the amount of ATP made in aerobic respiration | | | | |
 Question 6
2 out of 2 points | | | What is given off as a by-product of cellular respiration during the conversion of pyruvic acid (a three-carbon molecule) into acetyl-CoA (a two-carbon molecule)?Answer | | | | | Selected Answer: | CO2 | | | | |
 Question 7
2 out of 2 points | | | In cellular respiration, glucose, oxygen, and water are converted to ______.Answer | | | | | Selected Answer: | carbon dioxide, water, and ATP | | | | |
 Question 8
0 out of 2 points | | | Which of the following would best represent the progression of energy transformations that occur during aerobic cellular respiration?Answer | | | | | Selected Answer: | chemical energy stored in food → chemical energy stored in ATP → chemical energy stored in NADH | | | | |
 Question 9
2 out of 2 points | | | In aerobic cellular respiration, what is the "big picture" significance of glycolysis and the Krebs cycle?Answer | | | | | Selected Answer: | They allow for high-energy electrons and hydrogen ions to be collected for use in the electron transport chain. | | | | |
 Question 10
0 out of 2 points | | | What is a redox reaction?Answer | | | | | Selected Answer: | a reaction in which one molecule gains an oxygen atom and another molecule loses an oxygen atom | | | | |
