Photosynthesis occurs in two stages. In the first phase, light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. The energy for photosynthesis ultimately comes from absorbed photons and involves a reducing agent, which is (A)1.----- in the case of plants, releasing oxygen as a waste product.
During the second phase, the light-independent reactions (also called the (C) 2.----- Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture (B)3.----- and make the precursors of carbohydrates. |
1 - Water or H20
2 - Calvin or Calvin Benson 3 - Carbon Dioxide or CO2 |
