The light reactions of photosynthesis take place ______.
A) in the stroma
B) on the cristae
C) in the thylakoid membrane
D) in the cytosol

Question

Quizplus · Accepted Answer

The light reactions of photosynthesis take place in the thylakoid membrane, which is where the photosystems and electron transport chains are located. The stroma is where the dark reactions occur, also known as the Calvin cycle, which use the products of the light reactions to produce glucose. The cristae are part of the mitochondria and have nothing to do with photosynthesis. The cytosol is the fluid found within cells, but it is not where photosynthesis occurs.
