The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction. 6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2. where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars ...
