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 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). It is a form of ...
Endocytosis refers to when substances are taken into the cell, whereas for exocytosis substances are moved from the cell into the extracellular space. Material to be taken-in is surrounded by the plasma membrane, and then transferred to a vacuole. There are two types of endocytosis, phagocytosis (cell eating) and pinocytosis (cell drinking). In ...
It is an example of fluid phase endocytosis and is usually a continuous process within the cell. The particles are absorbed through the use of clathrin -coated pits. These clathrin-coated pits are short lived and serve only to form a vesicle for transfer of particles to the lysosome.
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).
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
Apart from endocytosis, some carriers are able to directly merge with the plasma membrane through fusion. Fusion events in biology include vesicle fusion, cell–cell fusion and cell–virus fusion. In these cases, juxtaposed membranes are pulled into close contact by specific protein–protein interactions and interfacial water is excluded to ...
