Photosynthesis Problem Set 1

Problem 4: Result of electron transport


During photosynthetic electron transport, the interior compartment of the thylakoid membranes becomes:
A enriched in ATP

B more acidic than the stroma

The concentration of protons can be nearly 1000 x higher inside the thylakoids than in the stroma during light reactions.

C basic compared to the reaction centers

D the site for glucose synthesis

E both more acidic than the stroma and enriched in ATP
