During the light-independent stage, plants need carbon dioxide from their environment to produce glucose.
The light-independent or synthetic stage takes place in the stroma of the chloroplasts, taking advantage of the molecules generated during the previous phase (ATP and NADPH).
Also known as the Calvin-Benson Cycle, synthesize organic substances through a circuit of chemical reactions, using different enzymes and taking advantage of carbon dioxide as the basis for the generation of glucose.
- Glucose is the food of the plant and the raw material that is used for the formation of other substances that it needs.
- The light-independent stage goes through the synthesis of fructose-phosphate and its transformation into glucose-phosphate; glucose-phosphate in turn reacts with ATP to give ADP-glucose, a compound capable of polymerizing to give starch.
Therefore, we can conclude that during the light-independent stage, plants need carbon dioxide from their environment to produce glucose.
