Which of the following equations best summarizes photosynthesis?
a) 6 co2 + 6 h2o + 6 o2 ? c6h12o6
b) 6 co2 + 6 h2o ? c6h12o6 + 6 o2
c) 6 co2 + 6 o2 ? c6h12o6 + 6 h2o
d) c6h12o6 + 6 o2 ? 6 co2 + 6 h2o

The correct answer is: B) 6 CO2 + 6 H2O ? C6H12O6 + 6 O2

Photosynthesis is a process of converting light energy to chemical energy in the form of sugars (carbohydrates). It is performed by plants, some algae and bacteria.

In the reaction of photosynthesis, sun energy combined with carbon dioxide (CO2) and water (H2O), to form glucose (C6H12O6) and oxygen (O2). Photosynthesis consists of two stages: the light-dependent reactions (in thylakoid membrane) where ATP is formed and the Calvin cycle (in stroma) where ATP is used.
