alleryIn a chloroplast, the light reactions take place in the
AThylakoid membranes of grana
BStroma of the chloroplast matrix
COuter membrane of the organelle
DIntermembrane space of the organelle
Answer & Solution
Correct answer: A. Thylakoid membranes of grana
Light reactions (photochemical phase) occur on the thylakoid membranes, where photosystems I and II are embedded.
The stroma houses the Calvin cycle (carbon reactions).
