vesicle fusion

Vesicle fusion is a process where small, membrane-bound sacs called vesicles merge with a target membrane, such as the cell membrane or an organelle’s membrane. This merging releases the vesicle’s contents into the surrounding environment or into the organelle’s interior. The process involves specific proteins that bring the vesicle and target membranes close together, overcoming repulsive forces, and coordinating their fusion. Vesicle fusion is essential for activities like transporting nutrients, releasing signals, and recycling cellular materials, ensuring proper cell function and communication.
