| Question | Answer |
|---|---|
| If a plant appears reddish yellos what wavelengths of visible light are not being absorbed by this pigment? | red and yellow |
| What are the products of noncyclic photophosphorylation? | ATP and NADPH |

| Where does glycolysis take place? | cytosol |
| What is the region of the enzyme that is involved in the catalytic reaction of the enzyme? | active site |
| What are the two locations in which ATP synthase complexes located? | thylakoid membrane & inner mitochondrial membrane |
