A logical consequence of the second law of thermodynamics could be stated,….  

  During photosynthesis, where do the carbon atoms in glucose come from?    

  In a given reaction, the energy needed to destabilize existing chemical bonds (take them to transition states) and actually start the chemical reaction is called the _________.  (hint: the “speed bump” for a reaction)    

  What stage of cellular respiration can occur in human cells with or without oxygen present?    

  It is summer, and you are excited about going to your local amusement park, and specifically about riding the new roller coaster that was just built.  You imagine waiting at the top of the stairs for the roller coaster to pull into the station, climbing into the car, strapping yourself into the seatbelt, and pulling down the harness.  You can imagine the cars slowly chugging up to the top of the first hill, coming down on the other side, and the excitement you expect to feel as you go along for the ride.  We discussed potential versus kinetic energy.  Of all of the things that you have imagined, which below is an example of potential energy?    

  What happens to the oxygen that is used in aerobic cellular respiration?     (hint:  think “final electron” acceptor of the ETC!)  

  In photosynthesis, carbon fixation occurs:    

  In glycolysis, a major portion of the energy remains in its final product, which is _________.   (hint:  what is the initial reactant/substrate and final products of glycolysis)  

  (easy math here!!!)  How many molecules of CO2 are needed to generate one molecule of glucose (C6H1206)?    

  All of the reactions of cellular respiration that occur after glycolysis take place in what part of the eukaryotic cell?
