TB 8.014 You incubate liposomes with a series of purified proteins normally found in the coats of cell transport vesicles.After adding one of them to the liposome mixture,budding of vesicles from the liposomes began.What does this mean?
A)Liposomes cause the protein to denature.
B)The protein is involved in the initiation of vesicle formation.
C)The protein is involved in liposome denaturation.
D)The protein triggers protein synthesis.
E)The protein causes the entry of water into the liposomes.

Question

Quizplus · Accepted Answer

The fact that the addition of one of the purified proteins resulted in budding of vesicles from the liposomes suggests that this protein is involved in the initiation of vesicle formation. Vesicle formation is a complex process that involves multiple proteins, including coat proteins, adaptor proteins, and motor proteins. These proteins work together to deform the membrane and form a small bud, which eventually pinches off to form a vesicle. The purified protein added to the liposome mixture likely functioned as a coat protein or an adaptor protein, which allowed the liposomes to form vesicles.
