Question 1 Report
2H2 → 2H2 + O2(g). The equation above represents a part of the light stage of photosynthesis. Which of the following must be presents for this reaction to occur?
Answer Details
The equation 2H2 → 2H2 + O2(g) represents the decomposition of water into hydrogen and oxygen gases during the light-dependent stage of photosynthesis. For this reaction to occur, light energy and chlorophyll must be present. Light energy is required to excite the electrons in the chlorophyll molecule, which are then used to split the water molecule into its component parts of hydrogen and oxygen. Enzymes are not required for this reaction to occur. Therefore, the correct answer is: Light energy and chlorophyll.
