Which of the following vesicle types does not bud directly from the trans-Golgi network?
A) Vesicles transporting plasma membrane receptors
B) Vesicles that form regulated secretory vesicles
C) Vesicles carrying lysosomal enzymes
D) Lysosomes

Question

Quizplus · Accepted Answer

Lysosomes are formed by the fusion of late endosomes/early lysosomes with each other and with vesicles from other intracellular compartments, such as the trans-Golgi network. Therefore, lysosomes do not bud directly from the trans-Golgi network. Vesicles transporting plasma membrane receptors bud directly from the trans-Golgi network and are then transported to the plasma membrane. Vesicles that form regulated secretory vesicles and vesicles carrying lysosomal enzymes also bud directly from the trans-Golgi network before being transported to their respective destinations.
