exocytosis
Yes, exocytosis is a bulk transport process where cells expel large molecules or particles by fusing vesicles with the cell membrane to release their contents outside the cell.
Exocytosis is the process by which cells release substances by vesicle fusion with the plasma membrane, allowing bulk transport of molecules out of the cell.
exocytosis
The process by which bulk materials are exported out of cells is called exocytosis. During exocytosis, vesicles containing the materials fuse with the cell membrane, allowing their contents to be released into the extracellular space. This process is vital for various cellular functions, including the secretion of hormones, neurotransmitters, and other essential substances. Exocytosis is an active process that requires energy in the form of ATP.

Bulk transport in cells is the movement of large quantities of molecules or particles across the cell membrane at once. This process helps in the efficient transport of substances such as proteins, polysaccharides, or even entire organelles. Bulk transport includes both endocytosis (taking in substances) and exocytosis (releasing substances).
Bulk transport, also known as bulk flow or vesicular transport, can occur in both directions relative to the concentration gradient. When substances are moved against their concentration gradient, this process is typically active transport, requiring energy (usually in the form of ATP). Conversely, when substances are moved along their concentration gradient, it is considered passive transport. Overall, bulk transport encompasses mechanisms that can handle both scenarios.
The movement of materials inside a cell is called intracellular transport, which includes processes like endocytosis, exocytosis, and vesicle transport. In multicellular organisms, the movement of materials between cells and tissues is facilitated by processes like diffusion, active transport, and bulk flow through specialized structures like blood vessels and lymphatics.
