The first stable product of the Calvin cycle in C3 plants is a:
Show answer and explanation
Correct answer: 3-carbon compound
The first stable product formed after CO2 fixation in the Calvin cycle is 3-phosphoglyceric acid (PGA), which contains three carbon atoms. This is why the cycle is referred to as the C3 pathway.
