Answer: The products of light-independent reactions are glucose and other organic compounds, which are essential for the survival of plants and other photosynthetic organ
Step-by-step explanation:
Light-independent reactions, also known as the Calvin cycle or the dark reactions, are a series of biochemical reactions that occur in the stroma of chloroplasts in photosynthetic organisms such as plants, algae, and some bacteria. These reactions are called "light-independent" because they do not require light energy to occur, unlike the light-dependent reactions that take place in the thylakoid membranes.
The Calvin cycle can be divided into three stages:
Carbon fixation: In this stage, atmospheric carbon dioxide (CO2) is captured by an enzyme called RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase) and added to a five-carbon sugar called ribulose bisphosphate (RuBP) to form a six-carbon molecule that quickly breaks down into two molecules of 3-phosphoglycerate (3-PGA).
Reduction: In this stage, ATP and NADPH, which are products of the light-dependent reactions, are used to convert the 3-PGA molecules into glyceraldehyde-3-phosphate (G3P), a three-carbon sugar.
Regeneration: In this stage, some of the G3P molecules are used to regenerate RuBP, which can then enter the carbon fixation stage again. The remaining G3P molecules are used to synthesize glucose and other organic compounds, which are the ultimate products of photosynthesis.
Overall, the net reaction of the Calvin cycle is:
6 CO2 + 18 ATP + 12 NADPH + 12 H+ → C6H12O6 (glucose) + 18 ADP + 18 Pi + 12 NADP+
The products of light-independent reactions are glucose and other organic compounds, which are essential for the survival of plants and other photosynthetic organ
