Gumdrop Glucose Models

Using marshmallows or gumdrops and toothpicks, build models of
glucose. You can look on the Internet to find various models for different
sugars. Pay particular attention to the way the parts are attached.
Now make color coded drawings of your models.
What are glucose molecules made up of? Does this suggest anything
about the water and carbon dioxide that are waste products when glucose
and oxygen are used in transforming energy in the mitochondria? Use
your models to help you think about this and write an reason.
