Vesicle Budding Recruits Proteins That are Needed for Subsequent

Question

Vesicle budding recruits proteins that are needed for subsequent:
A)invagination of the vesicle into the ER lumen.
B)selective vesicle targeting and fusion.
C)shedding of integral membrane proteins into the cytosol.
D)assembly of chromosome folding machinery.

Accepted Answer

Vesicle budding recruits proteins that are needed for selective vesicle targeting and fusion with target membranes. These include SNARE proteins, which bring the vesicle and target membranes into close proximity and facilitate the fusion process, as well as specific membrane receptors that help to ensure that the vesicle fuses with the correct target membrane. Invagination of the vesicle into the ER lumen and shedding of integral membrane proteins into the cytosol are not related to vesicle budding. Assembly of chromosome folding machinery is a process that occurs in the nucleus and is not related to vesicle budding.
