Membrane Traffic in Cells

Membrane traffic in cells moves materials between organelles and the cell surface. It helps cells sort, package, and deliver cargo to the right place. This process is essential for normal cell function.

Cells use membrane-bound compartments to handle this movement. Vesicles are small membrane sac...

Broadly, membrane trafficking can be of three categories. Cargo can be transported within the cell from one organelle to another using the secretory pathway or, into the cell using endocytosis, and out of the cell using exocytosis.

In the secretory pathway, substances produced inside the cell are packaged into protein-coated, membrane-bou...
