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 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.
Which process is occurring when a vesicle fuses with the cell membrane and releases its contents?
i believe you're referring to the process of exocytosis, when the contents of the vesicle are excreted into the area outside the cell as the vesicle fuses with the phospholipid bilayer and becomes part of it.
What are the steps of the secretory pathway?
Protein SynthesisEndoplasmic Reticulum-->cis Golgi cisternae --> medial Golgi cisternae --> trans Golgi Cisternae --> Plasma membraneExtra Cellular SpaceAs they are being synthesized, secretory proteins enter the lumen of the endoplasmic reticulum. From the ER, vesicles transport these proteins to the Golgi, where they are sequentially modified and concentrated in a cis-to-trans direction. Secretory vesicles bud from the Golgi and move along cytoskeletal filaments to eventually fuse with the plasma membrane, secreting their protein cargo. Each of these transport steps requires specialized proteins to ensure that the cargo is sent to the proper location and is able to fuse with the target membrane.
differentiate endocytosis from exocytosis?
Endocytosis:- It is the process by which cells take up substance from the external environment. In this a vesicle called endocytic vesicles get formed around the foreign substances. It occurs due to both phagocytosis and pinocytosis. In this internal vesicles are formed that are like phagosomes are formed The best known example is formation of food vacuole in amoeba. It is not involved in cell wall formation It involves transportation of macromolecules into the cell. At the end of this process the vesicle fuses with the membrane bound organelles. Exocytosis:- It is the process by which cells give up substance to the external environment. In this the vesicle that is filled with water gets fused with plasma membrane. It occurs due to regulated secretory pathways. The vesicle that is secretory in nature gets formed. The best known example is the hormone release. It is involved in cell wall formation. It is involved in transportation of macromolecules out of the cell. At the end of this process the vesicle gets connected with the cell membrane.
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 is a secretion vesicle?

What is an analogy for secretory vesicle?
A vesicle is something that transports things through cells, the same way buses transport passengers through a city. An analogy for a vesicle would be public transportation.
What packages proteins and other substances and deliver them to different parts of the 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 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 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 does a vesicle do in a cell?
Vesicle holds water for the cell
Trace the path of a protein from the time it is produced by a ribosome on the er until it reaches its destination?
A protein in the cell starts in the DNA. It is then translated into mRNA, goes into the ribosome, then the endoplasmic reticulum, followed by the Golgi apparatus and lastly the transport vesicles.
What is the name of the process in which an intracellular protein-containing vesicle fuses with the cell membrane and expels the protein to the outside of the cell?
A protein containing vesicle within a cell fuses with the cell membrane and ejects the protein is called exocytosis. A lysosome eats or ingests a bacterium is called phagocytosis.
What cell organelle is respnsible for moving protein through the cell?
A vesicle is the mode of transport for proteins to go where they need to go. The protein is packaged into a vesicle at the endoplasmic reticulum, and is brought to the Golgi apparatus or elsewhere in the cell.
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
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.
