问题 According to the first paragraph, when can we share our sweet drinks with our cell phones?
According to Paragraph 5, electrons are released

选项 A、when bags of enzyme are embedded in the new fuel cell.
B、when glucose from a sugary liquid goes through the enzyme.
C、when the enzyme oxidizes the glucose from a sugary liquid that goes through a pocket.
D、when the enzyme oxidizes the sugary liquid that goes through a pocket.

答案C

解析 该段第二句"When glucose from a sugary liquid penetrates a pocket, the enzyme oxidizes it, releasing electrons and proton." 中的it指代glucose,而不是a sugary liquid,因此C是正确选择。
