What is an analogy for a transport vesicle?
A good analogy for a transport vesicle would be a passenger vehicle, like a bus. The analogy could work in two ways: molecules are to a transport vesicle as passengers are to a bus, or a transport vesicle is to a cell as a bus is to a city.
What does a vesicle do in a cell?
Vesicle holds water for the cell
What are the steps involved in exocytosis?
It reorganizes its cytoskeleton to reposition its secretory vesicles at the plasma membrane. The vesicles then fuse to the plasma membrane using a complex interaction between proteins of the vesicle membrane and proteins of the cell membrane, and a realignment of the lipids of the membranes. This creates a fusion pore, which rapidly expands to expose the vesicle contents to the extracellular milieu. This releases the vesicle contents into the extracellular space.
What packages proteins and transports protein in a cell?
The Golgi Complex is responsible for packaging proteins and other substances and delivering them to different parts of the cell as and when needed. Golgi complex gathers simple molecules and combines them to make complex molecules and packages them in vesicles. It stores them for later use or sends them out of the cell. The Golgi Complex absorbs the transition vesicle that is released by the Endoplasmic Reticulum, once a protein is formed. Once the Golgi Complex processes the protein, it makes a secretory vesicle and releases it into the cytoplasm of the cell. The secretory vesicle moves towards the cell membrane from where the contents of the vesicle is released out of the cell.
What sentence best describes exocytosis?
Which sentence best describes exocytosis? A. a vesicle fuses to a lysosome and its contents are destroyed B. a vesicle fuses to the cell membrane and its contents enter the cell C. a vesicle fuses to the cell membrane and its contents leave the cell D. a vesicle fuses to the nuclear envelope and its contents enter the nucleus? Exocytosis is the durable, energy-consuming process by which a cell directs the contents of secretory vesicles out of the cell membrane into the extracellular space.
What does secretory vesicle do in animal cell?
They mostly secrete proteins...

What is a secretion vesicle?
there is no such thing as a secretion vesicle.although there is a secretory vesicle;Which is a membrane bound vesicle derived from the Golgi apparatus and containing material that is to be released from the cell.
What is the function of the secretory vesicle?
Vesicles perform many functions through complex mechanisms that can involve many aspects of cell regulation. Secretory vesicles in particular are specialized vesicles formed in the trans-golgi apparatus for releasing a product (such as molecule or protein) outside the cell. Secretory vesicles are used for exocytosis. Mast cells use secretory vesicles to release histamine which is a molecule involved immune response. Neurotransmitters can also be transmitted in secretory vesicles from nerve cells.
What is an analogy for pinocytotic vesicle?
A pinocytotic vesicle can be compared to a small "bubble" that forms inside a cell to transport liquids or small molecules into the cell. Just like how a bubble can encapsulate and transport something in the air or water, a pinocytotic vesicle encapsulates and transports substances inside a cell.
What is the difference between a transport vesicle and a secretory vesicle?
Transport vesicles Transport vesicles can move molecules between locations inside the cell, e.g., proteins from the rough endoplasmic reticulum to the Golgi apparatus. Membrane-bound and secreted proteins are made on ribosomes found in the rough endoplasmic reticulum. Most of these proteins mature in the Golgi apparatus before going to their final destination which may be to lysosomes, peroxisomes, or outside of the cell. These proteins travel within the cell inside of transport vesicles. Secretory vesicles Secretory vesicles contain materials that are to be excreted from the cell. Cells have many reasons to excrete materials. One reason is to dispose of wastes. Another reason is tied to the function of the cell. Within a larger organism, some cells are specialized to produce certain chemicals. These chemicals are stored in secretory vesicles and released when needed.
What are some things that endocytosis and exocytosis have in common?
They are both transporting molecules.Membrane-bounded vesicle. Exocytosis: is the durable process by which a cell directs the contents of secretory vesicles out etc
Question 5 text A secretory protein that exits from the ER within a vesicle will head directly to the?
A secretory protein that exits from the ER within a vesicle will head directly to the Golgi apparatus. It is an organelle that can be found in eukaryotic cells. It packages the proteins inside the cell before they are sent out to where they should be.
What packages proteins and other substances and deliver them to different parts of the cell?

Once the Golgi Complex processes the protein, it makes a secretory vesicle and releases it into the cytoplasm of the cell. The secretory vesicle moves towards the cell membrane from where the contents of the vesicle is released out of the cell.
What happens to a cell during the exocytosis?
It reorganizes its cytoskeleton to reposition its secretory vesicles at the plasma membrane. The vesicles then fuse to the plasma membrane using a complex interaction between proteins of the vesicle membrane and proteins of the cell membrane, and a realignment of the lipids of the membranes. This creates a fusion pore, which rapidly expands to expose the vesicle contents to the extracellular milieu. This releases the vesicle contents into the extracellular space.
How does a cell use exocytosis to release the contents of a vesicle outside of a cell?
In exocytosis, materials are exported out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill it's contents out of the cell.
