Where Does the Calvin Cycle Take Place

Question

Where does the Calvin cycle take place?
A)stroma of the chloroplast
B)thylakoid membrane
C)cytoplasm surrounding the chloroplast
D)interior of the thylakoid (thylakoid space)
E)outer membrane of the chloroplast

Accepted Answer

The Calvin cycle takes place in the stroma of the chloroplast. This is where the enzymes and other molecules necessary for the cycle are located. The thylakoid membrane is where the light-dependent reactions of photosynthesis occur, but the Calvin cycle is a light-independent process that takes place in the stroma. The cytoplasm and interior of the thylakoid are not involved in the Calvin cycle, and the outer membrane of the chloroplast only serves as a boundary.
