Which electron carrier molecule in the photosynthetic electron transport chain is largely hydrophobic and found floating in the thylakoid membrane?
A) heme
B) chlorophyll
C) pheophytin
D) plastoquinone

Question

Quizplus · Accepted Answer

Plastoquinone is a hydrophobic molecule that is found in the thylakoid membrane, where it functions as an electron carrier in the photosynthetic electron transport chain. Heme is not a primary electron carrier molecule in photosynthesis, and while chlorophyll and pheophytin are also found in the thylakoid membrane and play a role in photosynthesis, they are not largely hydrophobic like plastoquinone.
