Bulk endocytosis. Bulk endocytosis refers to a form of endocytosis of synaptic vesicles at nerve terminals. In bulk endocytosis, compared to clathrin-mediated endocytosis, a larger area of presynaptic plasma membrane is internalised as cisternae or endosomes from which multiple synaptic vesicles can subsequently bud off.
Pinocytosis. In cellular biology, pinocytosis, otherwise known as fluid endocytosis and bulk-phase pinocytosis, is a mode of endocytosis in which small molecules dissolved in extracellular fluid are brought into the cell through an invagination of the cell membrane, resulting in their containment within a small vesicle inside the cell.
Endocytosis. Endocytosis is a cellular process in which substances are brought into the cell. The material to be internalized is surrounded by an area of cell membrane, which then buds off inside the cell to form a vesicle containing the ingested materials. Endocytosis includes pinocytosis (cell drinking) and phagocytosis (cell eating).
Receptor-mediated endocytosis (RME), also called clathrin-mediated endocytosis, is a process by which cells absorb metabolites, hormones, proteins – and in some cases viruses – by the inward budding of the plasma membrane (invagination). This process forms vesicles containing the absorbed substances and is strictly mediated by receptors on ...
Endocytosis and exocytosis are both forms of bulk transport that move materials into and out of cells, respectively, via vesicles. [34] In the case of endocytosis, the cellular membrane folds around the desired materials outside the cell. [35] The ingested particle becomes trapped within a pouch, known as a vesicle, inside the cytoplasm.
Endocytosis: The membrane of the cell invaginates, creating a small circular pit that is taken into the cytosol of the cell. This circular membrane coated pit is a vesicle that is transported to the lysosome of the cell to be degraded by enzymes. -Cytosis is a suffix that either refers to certain aspects of cells ie cellular process or ...
The endomembrane system is composed of the different membranes (endomembranes) that are suspended in the cytoplasm within a eukaryotic cell. These membranes divide the cell into functional and structural compartments, or organelles. In eukaryotes the organelles of the endomembrane system include: the nuclear membrane, the endoplasmic reticulum ...
Transcytosis. Transcytosis (also known as cytopempsis) [1] is a type of transcellular transport in which various macromolecules are transported across the interior of a cell. Macromolecules are captured in vesicles on one side of the cell, drawn across the cell, and ejected on the other side. Examples of macromolecules transported include IgA ...
