1. tends to convert energy into matter.
2. will tend to gain useful energy
3. can become more ordered only if energy is added
4. inevitably becomes more disordered
5. can convert heat into work, but cannot convert work into heat

2. If ATP transfers energy to a muscle protein, the total of the energy released from the ATP_________.
i. can be used by the muscle to perform work
ii. will include energy used to do work and energy released as heat
iii. will be released as heat
iv. will include energy used to do work and energy that is destroyed in the transfer
v. is greater than the amount of energy added to the ATP during its synthesis

3. The synthesis of a protein from its component amino acids______ violate the Second Law of Thermodynamics because_______.

e. b and c

7. Two processes are said to be coupled when_______
1. if one takes place, the other must also take place
2. one process contributes energy to another process
3. the energy released by one equals the energy taken up by the other
4. both are exergonic or both are endergonic
5. a and b.

8. In order to drive an endergonic reaction by coupling it with a second reaction , the second Law of Thermodynamics requires that the second reaction_______ energy than/as the first requires.
a. release more
b. release less
c. release the same amount of
d. requires less
e. require more
