Given that photosynthetic cells have several light driven processes for generating ATP (cyclic and n

During dark reactions (Calvin cycle) in the stroma of the chloroplasts glycerate phosphate is produced.Now to make proteins the glycerate phosphate is converted to acetyl coenzyme A and fed into the Krebs cycle and converted into an acid in the MITOCHONDRIA. Then the acid combines with ammonia to form an amino acid and then to proteins by the process of protein synthesis in ribosomes.

In addition, at night it's dark. Chloroplasts don't make ATP when it is dark. Secondly, the chloroplasts don't share the ATP they make with the rest of the cell anyway. They use that to make carbohydrates.
