Question

which compound is a metabolic intermediate of the light - independent reactions in photosynthesis?
atp
pga
rubp
nadph

Explanation:

In the light - independent reactions (Calvin cycle) of photosynthesis, phosphoglyceric acid (PGA) is a metabolic intermediate. ATP and NADPH are energy - carrying molecules used in the cycle, and RuBP is the starting molecule that combines with carbon dioxide. PGA is formed when carbon dioxide is fixed to RuBP and then split.

Answer:

B. PGA
