What two components are required for the light reaction to take place?
- A.
Sunlight and carbondioxide
- B.
Soil and carbondioxide
- C.
Sunlight and water
- D.
Minerals and sunlight
Correct Answer
C. Sunlight and waterExplanation
In order to function and create both ATP and NADPH, the light reaction requires both sunlight and water.Rate this question:

After the breaking down of water molecules, which component is unusable to the plant and is thrown away?
- A.
Hydrogen
- B.
Oxygen
- C.
Air
- D.
Helium
Correct Answer
B. OxygenExplanation
After the water molecule is broken down, the oxygen is no longer needed and is released into the atmosphere.Rate this question:

- 4.
Which of the two reactions recycle 84% percent of their carbondioxide?
- A.
Dark reaction
- B.
Light reaction
Correct Answer
A. Dark reactionExplanation
The light reaction takes in both sunlight and water to create NADPH and ATP but does not recycle any of the components used. The dark reaction however, absorbs carbondioxide and uses the products of the light reaction to recycle every five out of six carbondioxide molecule it takes in. The other carbondioxide is used to make sugars for the plantRate this question:

- 5.
After both reactions, what is the end product of photosynthesis?
- A.
Fructose
- B.
Glucose
- C.
Oxygen
- D.
Both A and B are correct
Correct Answer(s)
A. Fructose
D. Both A and B are correctExplanation
The entire point of photosynthesis is to create both fructose and glucose.Rate this question:
