Which list below names the compartments into which chloroplast proteins can be imported?
A)inner and outer chloroplast membranes, the intermembrane space, the stroma, thylakoid membranes, thylakoid lumen
B)inner and outer chloroplast membranes, the intercristal space, the stroma, thylakoid membranes, thylakoid lumen
C)inner and outer chloroplast membranes, the intermembrane space, the cytoplasm, thylakoid membranes, thylakoid lumen
D)inner and medial chloroplast membranes, the intermembrane space, the stroma, thylakoid membranes, thylakoid lumen
E)inner and outer chloroplast membranes, the intermembrane space, the stroma, cristae membranes, thylakoid lumen

Question

Quizplus · Accepted Answer

Chloroplast proteins can be imported into the inner and outer chloroplast membranes, the intermembrane space between the membranes, the stroma (the fluid-filled region inside the chloroplast), the thylakoid membranes (which form the flattened disks where photosynthesis takes place), and the thylakoid lumen (the interior space of the thylakoid membranes). Choice B is incorrect because the intercristal space does not exist in chloroplasts. Choice C is incorrect because chloroplast proteins cannot be imported into the cytoplasm. Choice D is incorrect because there is no medial chloroplast membrane, and the membranes listed are not correct. Choice E is incorrect because cristae membranes are found in mitochondria, not chloroplasts.
