The number and arrangement of membranes within a chloroplast are important to the chloroplast's functions. How would the absence of these membranes affect the manufacture of ATP within a chloroplast?
A)The chloroplast would be unable to maintain the proton gradient required for ATP production.
B)The chloroplast would be unable to capture ATP directly from the sun.
C)The chloroplast would be unable to perform the Calvin cycle.
D)The chloroplast would be unable to perform anaerobic respiration.

The proton gradient across the inner membrane of the chloroplast is required for the production of ATP through the process of chemiosmosis. Without the membranes, there would be no proton gradient and therefore no ATP production. The other options given do not directly relate to the membranes within the chloroplast.
