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.

∙ 9y agoThe fluidity of the cell membrane enables it to form vesicles during the processes of endocytosis and exocytosis. The phospholipids in the membrane are capable of moving. This is due to the weak bonding between phospholipid tails as a result of bends which prevent them from being packed closely together. The presence of cholesterol in the also increases the membrane's fluidity.
Fluidity of cell membranes involved in endocytosis and exocytosis involves the extracellular matrix (ECM) and associated cell adhesion molecules (CAMs). Both ECM and CAMs are part of the microtubule "system" that give shape and function inside and outside the cell.

what uses vesicles to move substances out of a cell?
It is called exocytosis, which is defined as "a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane." The opposite of exocytosis is endocytosis.
Which process is occurring when a vesicles fuses with the cell membrane and releases its contents outside the cell?
osmosis
The Intake of small membrane vesicles from the extracellular fluid is called?
exocytosis
What do you think its right answer of the question Molecules that are too large to be moved across a cell membrane can be removed from the cell by endocytosis or exocytosis?
endocytosis
What is the process of expelling particles or liquids outside the cell membrane called?
The process by which the plasma membrane surrounds the substance inside the cell and moves it outside the cell is called EXOCYTOSIS.

When are endocytosis and exocytosis used?
Endocytosis is used when large materials can't get themselves in through the semi-permeable membrane. Exocytosis is used when the large material want to get out of the cell.

exocytosis
What is a function of the cell membrane that cannot be modeled with a plastic bag?
Endocytosis and exocytosis?
Types of bulk transport in cell?
Bulk transport is in 2 forms, exocytosis and endocytosis. Each of these 2 forms can then be sub divided into phagocytosis (movement of solids) and pinocytosis (movement of liquids) When bulk transport occurs, a phospholipid bilayer membrane merges with the cell membrane, and forces the contents of the vesicle in.out of the cell.

Exocytosis is the process by which .?
Exocytosis is the process by which the cell directs the contents of secretory vesicles out of the cell membrane. This process occurs through the fusion of the vacuole membrane with the cell membrane.
What occurs when the plasma membrane surrounds a large substance outside the cell and moves it inside the cell?
The process you are talking of is referred to as 'endocytosis', which is bulk transport into the cell.
What are the two major types of active transports?
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.
