A vesicle is a small, membrane-bound sac within a cell that transports and stores substances such as proteins, nutrients, and waste products. Membrane receptors are proteins located on the cell membrane that bind to specific molecules, such as hormones or neurotransmitters, triggering a cellular response. Together, vesicles and membrane receptors play crucial roles in intercellular communication and the transport of materials within and between cells.
What else can I help you with?
Where do receptor molecules end up after receptor-mediated endocytosis?
Its NOT 'on the inside surface of the cell membrane' Probably ' on the inside surface of the vesicle'
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
When the cell membrane becomes a vesicle?
When the cell membrane invaginates and pinches off, it forms a vesicle. This process is called endocytosis. The vesicle can then transport molecules or substances into or out of the cell.
Which of these neurotransmitters does not bind to a plasma membrane receptor?
Nitric oxide does not bind to a plasma membrane receptor.
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.
Where do receptor molecules end up after receptor-mediated endocytosis?
Its NOT 'on the inside surface of the cell membrane' Probably ' on the inside surface of the vesicle'
Is vesicle single or double membrane?
The vesicle is a single membrane, where a vacuole is a double membrane.
Two ways that the cells move things by active transport?
Endocytosis and exocytosis. Endocytosis is when the material goes in the cell by engulfing it in. There are different types of endocytosis: phagocytosis, pinocytosis, and receptor meditated. Phagocytosis is when the cell engulfs the material in the vesicle. Pinocytosis is when there is fluid in the vesicle. Receptor meditated is when there are receptors in the vesicle to attract material. Excocytosis is when the material goes out of the cell by fusing with the membrane. Both of these active transport uses a vesicle that forms in order to bring the materials in or out of the cell.

What happens to vesicle in exocytosis?
The vesicle fuses with the cell membrane, releasing it's contents.
Which process is occurring when a vesicle fuses with the cell membrane and releases its contents inside of the cell?
The process that occurs when a vesicle fuses with the cell membrane and releases its contents inside the cell is called exocytosis. Exocytosis is a form of active transport where the vesicle membrane merges with the cell membrane, allowing the vesicle contents to be released into the extracellular space or inside the cell.

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 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.
Most receptor proteins are embedded in the?
Receptor proteins are embedded in the lipid bilayer of the cell membrane.
Membranous sac formed by pinching off pieces of cell membrane?
vesicle/ vacuole
