What is a small sac that forms part of a cell membrane?
A vesicle forms as a small sac from the cell's membrane.
What is a exocytotic visicle?
An exocytotic vesicle is a membrane bound vesicle containing contents intended for release into the external environment. The vesicle will ultimately be fused with the cell membrane when its contents are released.
When a cell takes in substances through endocytosis the outside of the cell membrane becomes the inside of the vesicle. what might this suggest about the structure of the cell membrane?
This suggests that the cell membrane is a dynamic structure that can bend and invaginate to form vesicles during endocytosis. It is composed of a phospholipid bilayer with hydrophilic heads facing the aqueous environments (inside and outside) and hydrophobic tails sandwiched in between. The ability of the cell membrane to undergo endocytosis implies its flexibility and capability to change shape.
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.
When a vesicle fuses with the cell membrane to get rid of a particle what happens?
a vesicle does not fuse with the cell membrane. The cell membrane goes through endo- or exocytosis to absorb or eject a substance. In this case, exocytosis occurs, so the cell membrane engulfs the particle, pumps it through the membrane with the help of transport proteins, and then the vesicle breaks off and is gone.
What is the vesicle functions?
A vesicle in a cell is a bubble or sac of cell membrane that surrounds materials that need to be transported within or out of the cell.
What does it mean if the membrane structure of the final vesicle formed during exocytosis of the cell?
The cell membrane and vesicle have to be made of the same parts so that the process can be completed.
What happens to vesicle in exocytosis?
The vesicle fuses with the cell membrane, releasing it's contents.
What is a small sac that forms part of a cell membrane?
A vesicle forms as a small sac from the cell's membrane.
Membranous sac formed by pinching off pieces of cell membrane?
vesicle/ vacuole
What is a exocytotic visicle?
An exocytotic vesicle is a membrane bound vesicle containing contents intended for release into the external environment. The vesicle will ultimately be fused with the cell membrane when its contents are released.
What Membrane sac formed by pinching off pieces of cell membrane?
What cell is a non membrane bound?
vacoule, golgi vesicle
How does a ameoba?
Its called phagocytosis. Two extensions of the membrane called pseudopods surround the object to be engulfed. It then becomes a vesicle inside the cell which can be digested by lysosomes.

The ability of the cell membrane to undergo endocytosis implies its flexibility and capability to change shape.
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.
