When the contents of a vesicle are released by the cell?
Exocytosis is the process by which a cell releases the contents of a vesicle to the extracellular environment. This is important for functions such as hormone secretion, neurotransmitter release, and removing waste from the cell. During exocytosis, the vesicle membrane fuses with the cell membrane, allowing the contents to be expelled.
When a cell grows its plasma membrane expands does it involve exocytosis or endocytosis please explain?
I believe it's endocytosis, Because the cell takes in the food or the (transport) vesicles to grow " by the three types of endocytosis: Phagocytosis " Cellular eating " Pinocytosis " Cellular drinking " and " Receptor-mediated endocytosis " And they will fuse with the plasma membrane and become part of it, so accordingly, the plasma membrane is expanding.
What happens to a cell during the the process of endocytosis?
A process where cells absorb material molecules such as proteins from the outside by engulfing it with their cell membrane. It is used by all cells of the body because most substances important to them are large polar molecules, and thus cannot pass through the hydrophobic plasma membrane. The function of endocytosis is the opposite of exocytosis.
Endocytosis does not require that the cell use ATP?
Endocytosis can occur through different mechanisms such as phagocytosis, pinocytosis, and receptor-mediated endocytosis. While some forms may require ATP for the movement and rearrangement of cellular components during the process, there are also ATP-independent mechanisms. These include certain types of pinocytosis, where small molecules are taken up without the need for energy expenditure.
How does the structure of the cell membrane facilitate endocytosis and exocytosis?
Endocytosis is the process of the cell membrane engulfing a small amount of matter from the extracellular fluid. Therefore the structure of the cell membrane folds inward, and traps and encloses the matter so it is inside the cell. Exocytosis is just the reverse of endocytosis. It takes the amount of matter thats inside the cell and ejects it out. The structure of the cell membrane gets fused from a vesicle (thus restoring membrane removed in endocytosis). The contents of the outward-bound vesicle are secreted into the extracellular fluid.
What happens to the portion of the cell membrane the surrounds a large during endocytosis?

Substances outside a cell are transported into the cell by vesicles during?
Substances outside a cell are transported into the cell by vesicles during endocytosis. This process involves the formation of a vesicle that engulfs the particles or molecules outside the cell, then fuses with the cell membrane to bring the contents into the cell.
What happens to the portion of the cell membrane that surround a large molecule during endocytosis?
it separates from the membrane.
What happens to the portion of the cells membrane that surround a large molecule during endocytosis?
it separates from the membrane.
What happens to the portion of a cell membrane that surrounds a large molecule during endocytosis?
it separates from the membrane.
What is the process of expelling particles or liquids outside the cell membrane called?
The process of expelling particles or liquids outside the cell membrane is called exocytosis. During exocytosis, membrane-bound vesicles inside the cell fuse with the cell membrane and release their contents outside the cell. This process is important for transporting molecules out of the cell and maintaining cellular homeostasis.
Which is the process used by the cell to rid itself to unwant large substances?
Endocytosis where the substance will be surrounded by a cell membrane and then broken down for food or just discarded as waste.
