What would happen if a drug directly interfered with the functioning of RuBP carboxylase?
A)Water would not be split at the start of photosystem II,halting the light reactions.
B)Chemiosmosis and ATP production would cease,halting the Calvin cycle.
C)Carbon dioxide would not be fixed to RuBP,stalling the Calvin cycle.
D)RuBP would not be regenerated from G3P,halting the Calvin cycle.

Question

Quizplus · Accepted Answer

RuBP carboxylase, also known as Rubisco, is responsible for fixing carbon dioxide to RuBP in the Calvin cycle. If a drug interfered with its function, carbon fixation would be disrupted, stalling the Calvin cycle.
