the first stable intermediate product formed during dark reaction of photo synthesis is

1. ribulose-5-phosphate
2. phosphoglyceraldehyde
3. fructose-6-phosphate
4. glucose-1-phosphate

Hello Student
Correct Answer is 2. Phosphoglyceraldyde
Three molecules of CO₂combine with three molecules of RuBP to produce three molecules of an unstable 6-C compound, which immediately breaks sown into molecules of three phosphoglyceric acid phosphoglyceraldyde.
