Question

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.) Which of the answer choices would you expect to be directly affected by the new pesticide?A. the synthesis of triose phosphates from 3-phosphoglycerateB. the transport of electrons along the photosynthetic electron transport chainC. the carboxylation of RuBP by rubiscoD. the oxidation of RuBP by rubisco

Answer 1

Answer:

The correct answer will be option-A

Explanation:

The pesticide tested in the given question is thought to affect the production of ATP which slows down the metabolism of the plant and ultimately death of the plant.

Since the pesticide is not involved in inhibiting the process taking place in mitochondria, therefore, is thought to have affected the process outside the mitochondria of respiration that is in the cytosol.

The stage of respiration taking place in the cytosol is glycolysis. The conversion of  3-phosphoglycerate to triose phosphates results in the formation of ATP and is affected.

Thus, option-A is the correct answer.

Answer 2

Answer:

Option (A).

Explanation:

Pesticides are the chemicals used to kill the pests in the agricultural field. The pesticides includes the harmful chemicals that sometimes kill the non target organisms as well.

The new pesticide that has been discovered decreases the ATP production in chloroplast. The use of 3 phosphoglycerate will be effective in this case. The conversion of 3 phosphoglycerate into the triose will result in increase in ATP production in chloroplast.

Thus, the correct answer is option (A).
