B) Entropy increases and energy is used
C) Entropy decreases and energy is released
D) Entropy decreases and energy is used
E) There is no change in entropy or energy

5. When ATP releases energy, it also releases inorganic phosphate. What purpose does this serve (if
any) in the cell?
A) It is released as an excretory waste.
B) It is used exclusively to regenerate more ATP.
C) It can be added to water and excreted as a liquid.
D) It can be added to other molecules in order to activate them.
E) It can enter the nucleus to affect gene expression.
6. Which of the following metabolic processes requires a net input of energy from some other process
(i.e. is energy-requiring)?
A) ATP + H2O → ADP + Pi
B) C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
C) 6 CO2 + 6 H2O → C6H12O6 + 6 O2

A) Chemical work
B) Mechanical work
C) Osmosis work
D) Transport work
8. Nature’s tendency is to move toward a state of
A) Higher entropy, which means more disorder
B) Higher entropy, which means less disorder

9. A lion has to eat several gazelles per week to get sufficient energy. This is because:
A) Gazelles are fast and it takes a lot of energy to chase them
B) Gazelles can’t digest cellulose very efficiently
C) Lions have inefficient digestive systems that can’t digest cellulose
D) Lions are at the top of the food chain and the majority of the ecosystem’s energy has been lost
