A poison that disrupts the H ⁺ gradient in the thylakoid space would most likely cause which of the following to accumulate during the Calvin cycle reactions? A) 3-phosphoglycerate (3PG) B) ribulose 1,5-bisphosphate (RuBP) C) glyceraldehyde 3-phosphate (G3P) D) NADPH E) 1,3 bisphosphoglycerate (BPG)

Question

Quizplus · Accepted Answer

Disrupting the H+ gradient in the thylakoid space would impair ATP synthesis, which is necessary for the conversion of 3-phosphoglycerate (3PG) to 1,3-bisphosphoglycerate (BPG) in the Calvin cycle. This would lead to an accumulation of 3PG.
