If you tagged organic carbon inside a chloroplast with a fluorescent label,the location most likely to have a high concentration of labeled carbon would be in the
A)Stroma
B)Thylakoid membrane
C)Between the outer and inner membranes
D)Inside the thylakoid

Question

Quizplus · Accepted Answer

The stroma is the fluid-filled space inside the chloroplast where carbon fixation and other metabolic reactions occur. Organic carbon would be processed and synthesized in the stroma, making it the most likely location for high concentrations of labeled carbon. The thylakoid membrane and inside the thylakoid are primarily associated with the light-dependent reactions of photosynthesis, while the space between the outer and inner membranes is the intermembrane space and lacks chlorophyll or any other carbon-fixing machinery.
