How are large molecules taken into a cell
WebCells take up cholesterol from the LDL by means of LDL receptors in the outer cell membrane. The pathway for uptake involves several steps, including the following: The assembly of the receptor‐LDL complexes into a coated pit on the cell surface. The pit folds into a spherical endosome, which is a small vesicle of cell membrane with receptor ... WebLarge molecules, such as proteins and solid particles, are often transported by pinocytosis. The cell membrane engulfs a particle or protein molecule outside the cell, and brings it into the cell. Although inefficient, pinocytosis operates in the slow absorption of proteins and particles in the intestine and respiratory tract. Conditions of ...
