Endocytic Cycle
Most animal cells take up portions of their surface plasma membranes in a process called endocytosis. The main route of endocytosis is the coated pit, which buds into a cell to form a cytoplasmic vesicle — a clathrin-coated vesicle. The membrane so internalised is processed in a series of intracellular organelles, which include endosomes and lysosomes. Some of this membrane is returned to the cell surface by a process called exocytosis. The whole cycle of endocytosis plus exocytosis is known as the endocytic cycle.
The endocytic cycle is crucial for the survival of individual cells and multicellular organisms.

Famous quotes containing the word cycle:
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
