WebPhotosynthesis occurs in two stages, which are shown in Figure below. Stage I is called the light reactions. This stage uses water and changes light energy from the sun into chemical energy stored in ATP and NADPH (another energy-carrying molecule). This stage also releases oxygen as a waste product. Stage II is called the Calvin cycle. WebPhotosynthesis takes place inside chloroplasts which are small objects inside plant cells. Chloroplasts contain a green substance called chlorophyll. This traps the light energy …
