Intracellular transport refers to the movement of materials within a cell. This process is essential for distributing proteins, lipids, and other molecules to various parts of the cell, ensuring that cellular functions occur efficiently. Transport occurs through various mechanisms, including vesicles, which are small membrane-bound sacs that carry substances to their destinations. Key components involved in intracellular transport include microtubules and motor proteins. Microtubules form a network that acts like tracks for the movement of vesicles, while motor proteins, such as kinesin and dynein, use energy to transport these vesicles along the microtubules. This coordinated system is vital for maintaining cellular organization and function.
