Answer :
Final answer:
The compound that serves as a metabolic intermediate in the light-independent reactions of photosynthesis is RuBP, which is vital for carbon fixation. RuBP combines with carbon dioxide, and through a series of reactions, leads to the formation of carbohydrates. Thus, it is essential for the Calvin cycle to function properly.
Explanation:
Metabolic Intermediates in Photosynthesis
In the context of the light-independent reactions (Calvin cycle) of photosynthesis, the compound that acts as a metabolic intermediate is RuBP (Ribulose-1,5-bisphosphate). This molecule is essential in the Calvin cycle, as it combines with carbon dioxide (CO2) to eventually produce glucose and other carbohydrates.
The Calvin cycle uses energy stored in ATP and NADPH, generated during the light-dependent reactions, to drive the conversion of carbon dioxide into organic molecules. During this process, 3-PGA (3-phosphoglycerate) is formed and subsequently converted into another carbohydrate, G3P (glyceraldehyde-3-phosphate).
To summarize, RuBP is the crucial compound that must continuously enter the Calvin cycle for the light-independent reactions to proceed effectively.
