Molecular transport refers to the movement of individual molecules across cell membranes, often through processes like diffusion or facilitated diffusion, which occur at a cellular level. In contrast, bulk transport involves the movement of larger quantities of materials, such as groups of molecules or particles, typically through processes like endocytosis and exocytosis. While molecular transport is generally passive and driven by concentration gradients, bulk transport often requires energy input to move substances across membranes.
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.
exocytosis
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.
passive transport- diffusion, osmosis bulk/ active transport: requires energy ------------------------------------------- A+ -- exocytosis
Bulk transport is in 2 forms, exocytosis and endocytosis. Each of these 2 forms can then be sub divided into phagocytosis (movement of solids) and pinocytosis (movement of liquids) When bulk transport occurs, a phospholipid bilayer membrane merges with the cell membrane, and forces the contents of the vesicle in.out of the cell.
The difference between the two is that bulk motion is the flow through the capillary. Diffusion is the movement of the molecules in a fluid.Ê

The average cost of bulk transport varies, but it usually is three dollars and once cent per mile for the cost.
