Question

Quizplus · Accepted Answer

The Calvin cycle, also known as the dark reactions, occurs in the stroma of plant chloroplasts and in the cytosol of bacteria. Option A is incorrect because the lumen is the inner space of the thylakoid in chloroplasts. Option C is incorrect because grana lamellae are stacks of thylakoids, and the Calvin cycle does not occur there. Option D is incorrect because the plasma membrane is a structure found in all cells, but the Calvin cycle does not occur there. Option E is incorrect because the lumen and cytosol are not the locations where the Calvin cycle occurs.
