Retrograde transport

Retrograde transport is a cellular process where materials, such as proteins and other molecules, are moved from the outer parts of the cell back to the center or main compartment, like the cell’s nucleus or the Golgi apparatus. Think of it as a recycling or return system that helps cells retrieve and reuse key components, or send damaged or unnecessary items back for processing. This process is essential for maintaining cellular organization, function, and health, ensuring that proteins and other molecules are correctly routed and managed within the cell.
