QUESTION 5
The experiment conducted by Andre Jagendorf with isolatedthylakoid membranes proved that
possible solutions:
| | Blue and red light, but not green, caused photosyntheticproduction of oxygen |
| | The ATP synthase complex functioned as a molecular rotaryengine |
| | Molecular oxygen (O2) is derived from water, notCO2 |
| | ATP and NADPH are the direct products of the light reactions,not sugar |
| | ATP synthesis could be energized by a proton gradient |
QUESTION 6

possible solutions:
| | 3 and 3 respectively |
| | 1 and 1, respectively |
| | 3 and 2, respectively |
| | 2 and 3 respectively |
| | 4 and 4 respectively |
QUESTION 7
For every molecule of carbon dioxide (CO2)incorporated into sugar, how much ATP and NADPH are consumed?
Possible solutions:
| | 3 and 3 respectively |
| | 1 and 1, respectively |
| | 3 and 2, respectively |
| | 2 and 3 respectively |
| | 4 and 4 respectively |
QUESTION 8
When a plant is illuminated after a period of darkness, whatchanges occur in the environment of the chloroplast? Choose allthat are correct
Possible solutions:
| | The lumen pH increases |
| | The stroma pH increases |
| | The lumen pH decreases |
| | The stroma pH decreases |
| | Mg2+ in the stroma increases |
QUESTION 9
During the Calvin-Benson Cycle
Possible solutions:
| | Chemical energy of ATP and NADPH is used to create a membranepotential |
| | Chemical energy of ATP and NADPH is used to reduce carbondioxide to sugars |
| | Chemical energy of ATP and NADPH is used to oxidize carbondioxide to sugars |
| | Light energy is converted and stored directly by reducing carbondioxide and producing sugars |
| | Light energy is used to create chemical energy in the form ofATP and NADPH |
