What happens when chlorophyll is struck by sunlight?
The electrons in chlorophyll molecule become energized.
What makes certain molecules good electron carriers?
They can accept electrons and transfer most of their energy to another molecule.
Why are electron carriers needed for transporting electrons from one part of the chloroplast to another?
High-energy electrons are highly reactive.
A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The gas being collected is probably
Photosynthesis uses sunlight to convert water and carbon dioxide into
oxygen and high-energy sugars.
In the overall equation for photosynthesis, six molecules of carbon dioxide and six molecules of water result in a molecule of sugar and six molecules of
Which of the following is NOT a step in the light-dependent reactions?
ATP and NADPH are used to produce high-energy sugars.
What action contributes to the inside of the thylakoid membrane becoming positively charged during the light-dependent reactions?
H+ ions are released as water splits.
Which of the following is NOT a true statement about ATP?
Used ATP is discarded by the cell as waste.
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?
No sugars will be produced.
If you continue to increase the intensity of light that a plant receives, what happens?
The rate of photosynthesis increases and then levels off.
