Multiple Choice
In the process of photosynthesis, what molecule is primarily produced by Photosystem II during the light-dependent reactions?
A
Oxygen (O2)
B
Glucose (C6H12O6)
C
Carbon dioxide (CO2)
D
NADPH
Verified step by step guidance
1
Understand that photosynthesis consists of light-dependent reactions and the Calvin cycle. Photosystem II is part of the light-dependent reactions.
Recognize that Photosystem II is responsible for the initial step of capturing light energy to drive the splitting of water molecules.
Identify the process of photolysis in Photosystem II, where water molecules (H2O) are split into protons (H+), electrons, and oxygen (O2).
Acknowledge that the primary molecule produced by Photosystem II during the light-dependent reactions is oxygen (O2), released as a byproduct of water splitting.
Note that while NADPH is also produced in the light-dependent reactions, it is primarily associated with Photosystem I, not Photosystem II.
