Endocytosis
Videos
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

Receptor-mediated endocytosis, 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
Endocytosis
…by De Duve in 1963. Phagocytosis was discovered by Élie Metchnikoff in 1882. Endocytosis pathways can be subdivided into four categories: namely, receptor-mediated endocytosis (also known as clathrin-mediated endocytosis), caveolae, pinocytosis, and phagocytosis. Clathrin-mediated endocytosis is mediated by the production of…
Mechanism of clathrin-dependent endocytosis
Endocytosis is triggered when a specific receptor is activated in receptor-mediated endocytosis.
