A new experimental pesticide is being tested by a large agricultural chemical company. An unfortunate side effect in plants treated with this new product is a decrease in ATP production in the chloroplasts. (Interestingly, production of ATP in the mitochondria is unaffected.) Given this observation, which of the following would you expect to be DIRECTLY affected by the new pesticide?
A. the transport of electrons along the photosynthetic electron transport chain
B. the oxidation of RuBP by rubisco
C. the carboxylation of RuBP by rubisco
D. the synthesis of triose phosphates from 3-phosphoglycerate
