Question

which equation shows the overall process of photosynthesis?
a. c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o + energy
b. 6co₂ + 6h₂o + light energy → c₆h₁₂o₆ + 6o₂
c. 6o₂ + 6h₂o → 6co₂ + c₆h₁₂o₆
d. c₆h₁₂o₆ → co₂ + h₂o

Explanation:

Photosynthesis is the process by which plants, algae, and some bacteria use light energy to convert carbon - dioxide and water into glucose and oxygen. The correct equation should have carbon - dioxide and water as reactants, light energy as an input, and glucose and oxygen as products. Option A is the equation for cellular respiration. Option C and D are incorrect chemical equations for photosynthesis.

Answer:

B. 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
