DCMU is a small molecule that is often used as a herbicide (a chemical to kill plants). DCMU interrupts the electron transport chain in chloroplasts by blocking the donation of electrons by photosystem II to the electron transport chain. Explain the biochemical effects you would expect to see if you gave a plant cell DCMU, then measured for the following processes in the chloroplast in about 1 hour.

Specifically, predict if the following processes would increase, decrease or stay the same:

-Light absorption, production of ATP, production of G3P, usage of ATP.

-For each prediction, briefly explain why (1-2 sentences each).

The combustion of glucose ultimately involves the transfer of electrons to oxygen (O2). In biological systems, this takes place without a large increase in temperature. Which of the following statements about this process in biological systems is true?


1) Coupled oxidation-reduction reactions occur with electrons being passed to intermediate electron carriers.
2) The process involves the transfer of 12 pairs of electrons to oxygen.
3) The transfer of electrons from intermediate electron carriers to molecular oxygen is catalyzed by the electron transport chain.
4) Though the process is a controlled oxidation, some energy is lost.
