In the Calvin cycle, energy storage molecules from the light-dependent reactions are used to capture (fix) carbon dioxide molecules and build sugars. Learn more about how this important cycle works.
Check your understanding of photosynthesis!
How do you turn light energy into chemical energy? Find out how plants perform this amazing energy transformation. We'll dive into the properties of light, how chlorophylls and other pigments absorb light, and how the absorbed energy is stored in chemical bonds.
Photorespiration_C3_C4_and_CAM_plants
The Calvin cycle enzyme rubisco is essential...but it also has a bad habit. Rubisco sometimes acts on oxygen rather than carbon dioxide, leading to a carbon-wasting side process called photorespiration. Learn about the strategies C4 and CAM plants use to minimize photorespiration.
