What is a primary function of the cytoskeleton?

The primary function of the cytoskeleton is indeed to facilitate intracellular transport. The cytoskeleton is a dynamic network of protein filaments and tubules that provides structural support to the cell, much like a scaffold. This structure plays a crucial role in maintaining the shape of the cell and organizing its internal components.

In addition to providing structural support, the cytoskeleton is essential for cellular movement and the transport of materials within the cell. Motor proteins, such as kinesin and dynein, travel along the cytoskeletal tracks (microtubules and actin filaments) to move cellular cargo, including organelles, vesicles, and other materials, to their appropriate destinations. This efficient transport system is vital for various cellular processes, including division, signaling, and nutrient distribution.

Other functions mentioned in the choices, such as regulation of cellular metabolism, energy production through respiration, and storing genetic information, are not predominantly associated with the cytoskeleton and are managed by other cellular systems or organelles.
