Active transport requires energy provided by the cell for movement of materials across a membrane, while bulk movement is movement of solutes and liquid brought on by a pressure gradient.Oct 1, 2015 read more
Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell. Passive transport mechanisms Active Transport mechanisms . read more
Bulk flow is a form of passive transport. Diffusion, osmosis, electrodiffusion, current flow, and facilitated transport are all also forms of passive transport. read more
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. read more
