Where does the Calvin Cycle take place in plant cells?
A
In the cytoplasm
B
In the thylakoid membrane
C
In the mitochondria
D
In the stroma of the chloroplast
Verified step by step guidance1
Understand the structure of the chloroplast, which is the organelle where photosynthesis occurs in plant cells. It consists of the outer membrane, inner membrane, thylakoids, and stroma.
Recognize that the Calvin Cycle, also known as the light-independent reactions or dark reactions, is part of photosynthesis that does not require light directly.
Identify the location within the chloroplast where the Calvin Cycle occurs. The stroma is the fluid-filled space surrounding the thylakoids inside the chloroplast.
Recall that the Calvin Cycle uses ATP and NADPH produced in the light-dependent reactions (which occur in the thylakoid membranes) to convert carbon dioxide into glucose.
Conclude that the Calvin Cycle takes place in the stroma of the chloroplast, where the necessary enzymes and substrates are available for the cycle to proceed.
