Is bulk transport the same as vesicular transport in biological cells?

Click For Summary
SUMMARY

Bulk transport and vesicular transport are closely related processes in biological cells, but they are not identical. Bulk transport refers to the movement of macromolecules across the cell membrane, which includes both endocytosis (incoming transport) and exocytosis (outgoing transport). Vesicular transport specifically involves the use of vesicles to facilitate this movement. The analogy of a shipping company using trucks to move items highlights the distinction: bulk transport is the overall process, while vesicular transport is the mechanism employed within that process.

PREREQUISITES

In the biological cell, is the bulk transport the same as the vesicular transport?

I read about them separately and found that they happen in the same way, so I guessed that they are the same thing, or am I wrong?
 
Biology news on Phys.org
Mostly the same. Bulk transport is the movement of macromolecules through the membrane, in or out of the cell. When endocytosis occurs (incoming) vesicles are loaded with the molecules. For exocytosis (outbound) vesicles attach to the cell membrane and the molecules in the vesicle get passed out.

So vesicular transport is in-cell movement, bulk transport is the entire process -
kind of like a shipping company(bulk transport) uses trucks (vesicles) to move items either in or out of the city using a common warehouse (membrane).

Do not overthink the analogy, it is just to get a feel for the slight distinction most often used.
