Sec23 and Sec24 bind together to form a "banana-shaped" dimer. What is the purpose of this dimer?
A)Because of its linear shape, it firms up the membrane.
B)Because of its curved shape, the dimer puts pressure on the membrane surface to help it further bend into a curved bud.
C)Because of its curved shape, the dimer puts pressure on the membrane surface to help it disintegrate.
D)The dimer stabilizes the Golgi complex membrane.
E)The dimer joins with other dimers to form a remarkably stable cage.

The curved shape of the Sec23-Sec24 dimer puts pressure on the membrane surface to help it further bend into a curved bud during vesicle formation. This helps contribute to the specificity and directionality of cargo transport within the cell.
