2. What is the 1st Law of Thermodynamics? If living things cannot create or destroy energy, where do they get their energy from (answer hint: it is a characteristic of life...see chapter 1)?
3. What does the 2nd Law of Thermodynamics state?
4. In relationship to the 2nd Law of Thermodynamics, every energy transformation involves a loss of energy in the form of ________. Therefore, _________ energy would not be useful to living things.
5. Every chemical reaction involves the ________ and ______ of new chemical bonds. As seen when sucrase converts sucrose into glucose and fructose.
6. What is the thermodymic barrier that reatants must overcome in chemical reactions to form products? (Hint: It is a type of energy we discussed in class.)
