问题  Your muscles are working to move a weight when you are ______.
  Glucose can be completely broken down into carbon dioxide and water when oxygen is present in the process called ______.
选项 A、anaerobic metabolism
B、aerobic respiration
C、burning ATP
D、phosphagen system
答案C
解析 根据题干信息词carbon dioxide，oxygen定位到第五个小标题下的第一段第二句When oxygen is present， glucose can be completely broken down into carbon dioxide and water in a process called aerobic respiration，由此可知两分钟的运动后，身体会向活动的肌肉供应氧气，供应到氧气时，葡萄糖将分解为二氧化碳和水，这种变化是在被称作有氧呼吸(aerobic respiration)的过程中发生的，故本题选C。
