Bulk or Vesicular Transport Quiz

Substances such as proteins, carbohydrates, and lipids that are too large to pass through the cell membrane by simple diffusion or active transport.

A small, membrane-bound sac that transports materials within and out of the cell.

The process by which large molecules are transported into or out of the cell using vesicles.

The process by which a vesicle buds off from a membrane. It's like a balloon being pinched off.

The process by which a vesicle fuses with a membrane. This is like releasing the contents of a package.

Coat proteins help in selecting and packaging cargo molecules into vesicles. They are like specific tags for the cargo.

The process by which a vesicle is released from its coat proteins. It's like unwrapping a package.

The movement of a vesicle to its destination. It's like driving a truck to the right address.

The process where a vesicle detaches from a donor membrane and forms a closed, spherical structure.

The process that severs the vesicle neck from the donor membrane, allowing the vesicle to completely detach.

The process where the protein coat surrounding the vesicle is removed, exposing the vesicle membrane.

The movement of the vesicle from its origin to its destination.

The process where the vesicle interacts with specific proteins on the target membrane, allowing it to attach.

The final step in vesicular transport, where the vesicle membrane fuses with the target membrane, releasing its contents.

A mnemonic acronym to remember the six steps of bulk transport: Budding, Scission, Uncoating, Translocation, Tethering, Fusion.

Vesicular transport is categorized based on destination and cargo type. For example, endocytosis is the process of bringing material inside the cell, while exocytosis releases material outside the cell.

A type of active transport where large molecules are moved into or out of the cell using vesicles.

Vesicular transport that moves materials out of the cell. A vesicle fuses with the plasma membrane, releasing its contents outside the cell.

A type of endocytosis where the cell engulfs large solid particles, such as bacteria or debris, forming a phagosome.

A type of endocytosis where the cell engulfs small droplets of extracellular fluid, including dissolved molecules.

A specialized type of endocytosis where the cell takes in specific molecules by binding to receptor proteins on the plasma membrane. This leads to the formation of a coated vesicle.

Large molecules, like proteins, can be transported out of the cell through exocytosis using vesicles that fuse with the plasma membrane.

Electrolytes, small charged molecules, can enter the cell through endocytosis, specifically pinocytosis. The cell takes in small droplets of extracellular fluid containing these molecules.

Pathogens are large molecules that can be engulfed by white blood cells through phagocytosis, forming a phagosome. The white blood cell will then destroy the pathogen.

The process of transporting large molecules across a cell membrane using vesicles, which are small membrane-bound sacs.
