PPT-Endocytosis & Exocytosis

Endocytosis process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane Pinocytosis cellular drinking occurs when the plasma membrane folds inward to form a channel allowing dissolved substances to enter the cell. Diffusion. : The passive movement of particles from a region of high concentration to a region of low concentration until equilibrium is reached. (Molecules still move after equilibrium is reached) .

Endocytosis. is a process by which cells absorb molecules (such as proteins) by engulfing them. It is used by all cells of the body because most substances important to them are large polar molecules that cannot pass through the hydrophobic plasma or cell membrane.. -. Gateway to the Cell. 2.

CONCEPT 5.5: Bulk transport across the plasma membrane occurs by exocytosis and endocytosis. Small solutes and water enter or leave the cell through the lipid bilayer or by means of transport proteins. Chapter 3. Cell Membrane.

By processes of endocytosis and exocytosis, vesicles help cells take in and expel particles that are too big for transport proteins, as well as substances in bulk.
