Like the active transport processes that move ions and small molecules via carrier proteins, bulk transport is an energy-requiring (and, in fact, energy-intensive) process. Here, we’ll look at the different modes of bulk transport: phagocytosis, pinocytosis, receptor-mediated endocytosis, and exocytosis.
Active transport methods require the direct use of ATP to fuel the transport. Large particles, such as macromolecules, parts of cells, or whole cells, can be engulfed by other cells in a process called phagocytosis.
Aug 3, 2023 · Bulk Transport is a cellular process by which large amounts of material are transported in or out of the cell in membrane-bound sacs called cysts. The membrane is held together by weak hydrophobic associations between fatty acid tails by phospholipids.
Bulk transport is the term used to describe the passage of big molecules or particles through the endocytosis and exocytosis processes across the cell membrane.
Endocytosis is a type of active transport that moves particles, such as large molecules, parts of cells, and even whole cells, into a cell. There are different variations of endocytosis, but all share a common characteristic: The plasma membrane of the cell invaginates, forming a pocket around the target particle.
Bulk Transport – Biology Part I. 45 Bulk Transport. Learning Objectives. By the end of this section, you will be able to do the following: Describe endocytosis, including phagocytosis, pinocytosis, and receptor-mediated endocytosis. Understand the process of exocytosis.
Bulk transport. The processes of diffusion, osmosis and active transport are responsible for the transport of individual molecules or ions across cell membranes. However, the bulk transport of larger quantities of materials into or out of cells is also possible.
