Secretory vesicles pinch off from what?
Secretory vesicles pinch off from the Golgi apparatus during the process of exocytosis. These vesicles contain proteins or other molecules destined to be secreted from the cell. Once they pinch off, they move towards the cell membrane to release their contents outside the 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 packages substances for release from a cell?
Vesicles, such as synaptic vesicles and secretory vesicles, are responsible for packaging various substances inside a cell before releasing them. These vesicles transport molecules out of the cell membrane through processes like exocytosis, allowing for the controlled release of substances.
What is the apparatus membranes thought to be responisable for secretion?
The Golgi apparatus is responsible for sorting, modifying, and packaging proteins and lipids into vesicles for secretion. The secretory vesicles are then transported to the cell membrane for release of their contents outside the cell.
What are related to the secretory activity of the cell?
The secretory activity of a cell is primarily related to organelles such as the endoplasmic reticulum (ER), Golgi apparatus, and vesicles. The rough ER synthesizes proteins, while the smooth ER is involved in lipid synthesis and detoxification. After proteins are synthesized, they are modified and packaged in the Golgi apparatus for secretion. Vesicles transport these modified substances to the cell membrane for exocytosis, releasing them outside the cell.
What forms secretory vesicles?
Secretory vesicles can form from the Golgi apparatus, which packages proteins and molecules for secretion. These vesicles can also be formed from endosomes that have internalized molecules or from specialized secretory cells in the body. Once formed, secretory vesicles move towards the cell membrane for exocytosis to release their contents outside the cell.
What the function of secretory vesicles?
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 do Golgi apparatus do for the animal cell?
it modifies substances produce by the ER(endoplasmic reticulum) and packages the subs into secretory vesicles.

What does the secretory vesicles do in animal cells?
They mostly secrete proteins...
How does secretory vesicles function?
membrane bound structures that are responsible for the transportation of molecules in and out of a cell

Which organelle receives transport vesicles from the endoplasmic reticulum and produces lysosomes and secretory vesicles?
The Golgi apparatus receives transport vesicles from the endoplasmic reticulum and processes them. It modifies, sorts, and packages proteins into lysosomes and secretory vesicles for transport to different parts of the cell or outside the cell.

What carries secretions for export from cell?
Secretions for export from a cell are carried by vesicles, which are membrane-bound compartments that transport substances within the cell. The secretory vesicles typically fuse with the cell membrane to release their contents outside the cell.
Which organelle packages proteins in vesicles and sends them to the body where they are need?
Golgi apparatus
