Which of the following chemical equations summarizes the reactions in photosynthesis?
A
C6H12O6 + 6 H2O → 6 CO2 + 12 H2O
B
2 H2O + 2 CO2 → C2H4 + 3 O2
C
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy
D
6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2
Verified step by step guidance1
Understand the process of photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose. The general equation for photosynthesis is: 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2.
Identify the reactants and products: In photosynthesis, the reactants are carbon dioxide (CO2) and water (H2O), and the products are glucose (C6H12O6) and oxygen (O2). Light energy is also a crucial component of the reaction.
Compare the given equations: Analyze each of the provided chemical equations to determine which one matches the general equation for photosynthesis. Look for the presence of CO2 and H2O as reactants and C6H12O6 and O2 as products.
Evaluate the role of energy: In photosynthesis, light energy is absorbed by chlorophyll and used to convert CO2 and H2O into glucose and oxygen. Ensure that the equation reflects the input of light energy, which is a key aspect of the process.
Select the correct equation: Based on the analysis, choose the equation that accurately represents the photosynthesis process, which is 6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2.
