Which compound is a metabolic intermediate of the light-independent reactions in photosynthesis?

A. ATP
B. PGA
C. RuBP
D. NADPH

Answer :

Final answer:

RuBP is a metabolic intermediate of the light-independent reactions in photosynthesis, where it combines with CO2 to form PGA.


Explanation:

The compound that is a metabolic intermediate of the light-independent reactions in photosynthesis is RuBP (ribulose bisphosphate).


During the light-independent reactions, also known as the Calvin cycle, RuBP combines with carbon dioxide (CO2) to form two molecules of a three-carbon compound called PGA (phosphoglycerate). PGA is then further modified and eventually converted back into RuBP to continue the cycle.


RuBP is therefore an essential compound in the overall process of photosynthesis as it enables the fixation of carbon dioxide and the synthesis of organic molecules.
