Which of the Following is Associated with the Calvin-Benson Cycle

Question

Which of the following is associated with the Calvin-Benson cycle?
A) acetyl-CoA
B) TMAO
C) RuBP
D) FADH₂
E) PABA

Accepted Answer

The Calvin-Benson cycle is a metabolic pathway used by plants and other photosynthetic organisms to convert carbon dioxide from the atmosphere into energy-rich molecules like glucose. The cycle begins with the enzyme Rubisco attaching carbon dioxide to a five-carbon sugar called ribulose-1,5-bisphosphate (RuBP). This produces two molecules of a three-carbon sugar called 3-phosphoglycerate, which are then converted into glucose. Therefore, C, RuBP, is associated with the Calvin-Benson cycle.
