Unit 10 Target 2: Photosynthesis Quiz

1. If carbon dioxide is completely removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars?

More sugars will be produced.

No sugars will be produced.

The same number of sugars will be produced but without carbon dioxide.

Carbon dioxide does not affect the production of high-energy sugars in plants.

2. What is the correct sequence of events during photosynthesis?

Chemiosmosis > light absorption > Calvic cycle > electron transport chain

Light absorption > electron transport chain > chemiosmosis > calvin cycle

Light absorption > electron transport chain > calvin cycle > chemiosmosis

Chemiosmosis > light absorption > electron transport chain > calvin cycle

3. Which step is the beginning of photosynthesis?

ATP synthase allows H+ ions to pass through the thylakoid memebrane.

None of the above

13. In the overall equation for photosynthesis, 6 molecules of carbon dioxide result in which of the following?

1 glucose

6 water

6 ATP

2 oxygen

14. Thylakoid membranes within chloroplasts contain chlorophyll. The Calvin cycle (light-independent reaction) occurs in the stroma of the chloroplasts. How are the processes occurring within the Calvin cycle and the thylakoid membrane connected?

The processes in the thylakoid membrane use sugar molecules formed during the Calvin cycle to generate high-energy molecules.

The processes in the thylakoid membrane use high-energy molecules formed during the Calvin cycle to convert CO2 into sugar molecules

The Calvin cycle uses sugar molecules formed within the thylakoid membrane to generate high-energy molecules.

The Calvin cycle uses high-energy molecules formed within the thylakoid membrane to convert CO2 into sugar molecules.
