Answer key
Section 1
1. ATP
2. Muscle contraction, active transport, growth, reproduction
3. release energy, form ADP, release small amount of heat, release Pi
4. ATP, heat
5. autotrophs
6. sun
7. plants use sun to form glucose, animals eat plants, animals eat other animals
8. cellular respiration
Section 2
1. photosynthesis
2. chlorophyll
3. red (675 nm) and blue (450 nm)
4. green wavelengths (525 nm) are reflected
5. oxygen gas (O2)
6. enter the electron transport chain of the thylakoid membrane

transport chain)
9. without air, without oxygen or in the absence of oxygen
10. 2 ATP (2 from glycolysis, 0 from fermentation)
11. anaerobic respiration or fermentation)
12. alcoholic fermentation, lactic acid fermentation
13. membrane of the mitochondrion
14. 32 ATP and 6 H20
