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 the partial inhibition of ferredoxin-NADP⁺ reductase. Given this observation, which of the following would you expect to observe in the photosynthetic cells of these plants? A)decreased rate of triose phosphate production B)decreased levels of NADP⁺in the chloroplast C)decreased levels of ATP in the chloroplast D)decreased rate of cyclic electron transport

Question

Ferredoxin-NADP+ reductase plays a crucial role in the production of NADPH, which is necessary for the reduction of carbon dioxide in photosynthesis. Therefore, partial inhibition of this enzyme would lead to a decreased rate of triose phosphate production, as the amount of available NADPH for carbon fixation is reduced. The other choices are not directly related to the inhibition of this enzyme.
