How does the food we eat actually give us energy?

    I know it has to due with the calories and such that we are consuming, but how does the food help to actually 'wake us up'?

    Jerglove, we could likely better help answer your question if you give us a little more background. What types of biology classes have you had, if any, and if you're still in school, what grade are you in?
