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。
