Question

If light energy was involved in the process, which of these reactions would represent photosynthesis as cyanobacteria would carry it out?

1) 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O2
2) 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O2 + light energy
3) C₆H₁₂O₆ + 6O2 + light energy → 6CO₂ + 6H₂O
4) C₆H₁₂O₆ + 6O2 → 6CO₂ + 6H₂O + light energy

Answer 1

The correct reaction representing photosynthesis as cyanobacteria would carry it out is '6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂', where light energy converts carbon dioxide and water into glucose and oxygen.

Step-by-step explanation:

The process of photosynthesis involves the conversion of light energy into chemical energy which is stored in glucose. Cyanobacteria, like plants, carry out photosynthesis using light energy to convert carbon dioxide and water into glucose and oxygen. The correct equation that represents this process is as follows: 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂. This equation shows that carbon dioxide and water, in the presence of light energy, produce glucose and oxygen.
