Describe one example given in class that illustrates the concept: "Metabolic pathways are not randomly ordered reactions, instead they obey clear chemical logic." (for full credit you must give the example AND an explanation of the chemical logic)

It depends whether you're talking about catabolism or anabolism. If you're creating new organic compounds, then it's an anabolic reaction. That way, ATP will be broken down, so as to fuel the chemical reactions. However, if you are talking about catabolic reactions, in which you aim to obtain ATP, by means of degradation of certain substances, in that case the right answer would be II.
