Biology Question on respiration in plants
In C3 plants, the first stable product of photosynthesis during the dark reaction is
A
Oxaloacetic acid
B
3-phosphoglyceric acid
C
Phosphoglyceraldehyde
D
Malic acid
Answer
3-phosphoglyceric acid
Explanation
Solution
3-phosphoglyceric acid is the initial stable product of photosynthesis in the dark reaction. It is generated when ribulose-1,5-bisphosphate (RuBP) reacts with carbon dioxide (CO2) in the presence of the enzyme RuBisCo.
