A researcher applies a toxin to a species of green algae to block the regeneration of ribulose bisphosphate. She then supplies CO2, labeled 14C, to the algae. Finally, she washes away the toxin to restore the regeneration of ribulose bisphosphate. Where is 14C expected to be found before and after the toxin is washed away?

Before, it should be found in glyceraldehyde-3-phosphate, but not in ribulose bisphosphate. After, it should be found in glyceraldehyde-3-phosphate, but not in ribulose bisphosphate.

Before, it should be found in glyceraldehyde-3-phosphate, but not in ribulose bisphosphate. After, it should be found in both glyceraldehyde-3-phosphate and ribulose bisphosphate.
