1. Consider what happens to the heat that is released from energy transfers on earth. Think about how this is related to the greenhouse effect.
2. Discuss how life can be so organized when the level of entropy in the universe continues to increase. The universe as a whole contains more entropy, while an individual cell, organism, or ecosystem must be considered as an open system that requires a continuous energy input to maintain its organization.
3. Consider how an enzyme can lower the activation energy for a reaction and why there is an energy of activation even for a spontaneous reaction.
4. Discuss how changes in various conditions and inhibitors can affect the structure of an enzyme and thus its ability to interact with a substrate to catalyze the enzymatic reaction.
5. Discuss why vitamins are required only in small amounts and how they are active in the cell.
6. Describe how coupled reactions using ATP allow
reactions that require energy input to take place in the cell
under conditions that are compatible with life.
