How do larger molecules move across epithelial membranes in the capillaries?
Larger molecules can cross epithelial membranes in capillaries through processes like transcytosis, where the molecule is taken up by the cell on one side and transported across the cell to be released on the other side. This process often involves vesicles that transport the molecule across the cell.
What would you expect to find in exocytotic vesicles?
Exocytotic vesicles typically contain molecules such as hormones, neurotransmitters, digestive enzymes, or other proteins that need to be released from the cell. These vesicles fuse with the cell membrane to release their cargo outside of the cell through the process of exocytosis.
What are vesicles and what do they do?
Vesicles are small membrane-bound sacs that transport material within cells. They can move molecules, such as proteins or lipids, between different parts of the cell or to the cell membrane for secretion. Vesicles are crucial for maintaining cellular structure and function.
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.
In which process does a cell use a vesicle to move molecules out of the cell?
exocytosis
In which process dose the cell use a vesicle to move molecules out of the cell?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
Which process does the cell use a vesicles to move molecules into the cell?

What process does a cell us a vesicle to move molecules out of a cell?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
What process does the cell use a vesicle to move molecules out of a cell?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
What process does the cell use a vesicle to move molecules out of the cells?
Exocytosis is the process that moves molecules from the inside of the cell to the outside. This process uses sacs or vesicles to move the molecules out.
What process does a cell use a vesicle to move molecules into the cell?
None - it would use vesicles to move stuff out of itself.
What direction do molecules move in exocytosis?
In exocytosis, molecules move from inside the cell to outside the cell. This process involves the fusion of vesicles with the cell membrane, releasing the contents of the vesicles into the extracellular space.
In which process does the cell use a vessel to move molecules out of the cell?
The process in which a cell uses a vessel to move molecules out of the cell is called exocytosis. During exocytosis, vesicles containing the molecules fuse with the cell membrane, releasing their contents into the extracellular space. This mechanism is essential for processes such as hormone secretion and neurotransmitter release.

In which process does the cell use a vesicles to move molecule out?
Exocytosis
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.

Exocytosis
