Cells from a banana fruit are kept without oxygen and form ethanol and carbon dioxide. Cells from a celery stem use oxygen and form carbon dioxide and water. Each group breaks down the same number of glucose molecules.
Which comparison is correct?
The products from the banana cells contain more chemical energy because their glucose is broken down incompletely
The products from neither group contain chemical energy because both groups release carbon dioxide
The products from both groups contain the same chemical energy because equal amounts of glucose are used
The products from the celery cells contain more chemical energy because oxygen is used during respiration
