WebSeveral steps require the ATP or NADPH generated by the light reactions. In addition, some of the enzymes are fully active only when conditions simulate those in green cells exposed to light. In living plants, these enzymes are active during photosynthesis but not in the dark. The Calvin-Benson 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 needed to make...
