Detail about Mcqs
The correct answer is:
C. 2H, 2e, and 1/2 O₂
Explanation:
During the light-dependent phase of photosynthesis:
Photolysis of water occurs, which is the splitting of water molecules into their components using light energy.
The reaction is:
2H2O→4H++4e−+O2
For one molecule of water:
H2O→2H+ +2e− +1/2 O2
Thus, for every water molecule broken down:
2 protons (H⁺) are released.
2 electrons (e⁻) are released.
1/2 molecule of oxygen (O₂) is produced.
