A

3-PGA

B

Text Solution

Verified by Experts

The correct Answer is:
B
Malic acid produced from oxaloacetic acid during the night is stored in the plant cells vacuole during the daytime this malic acid is broken down to release `CO_2` and phosphoenolpyruvate. The `CO_2` produced binds with RUBP to give 3 – PGA and carry out the C3 cycle.
