Vesicle transport is a cellular process that involves the movement of small, membrane-bound sacs called vesicles. These vesicles carry proteins, lipids, and other molecules within a cell or to the cell's exterior. This transport is essential for various functions, including secretion, nutrient uptake, and waste removal. The process typically involves the formation of vesicles from cellular membranes, which then travel along microtubules with the help of motor proteins. Once they reach their destination, the vesicles fuse with target membranes, releasing their contents where needed. This mechanism is crucial for maintaining cellular organization and communication.
