Verified step by step guidance
1
Understand the role of the cytoskeleton: The cytoskeleton is a network of fibers that provides structural support to the cell and plays a role in intracellular transport.
Identify the components of the cytoskeleton: The main components are microtubules, microfilaments (actin filaments), and intermediate filaments.
Recognize the function of microtubules: Microtubules are hollow tubes that serve as tracks for motor proteins, such as kinesin and dynein, to transport vesicles and organelles within the cell.
Differentiate between the components: Microfilaments are primarily involved in cell movement and shape, while intermediate filaments provide mechanical support. Microtubules are specifically used for transport.
Conclude that motor proteins use microtubules for vesicle transport: Given their structure and function, microtubules are the correct component of the cytoskeleton used by motor proteins to transport vesicles.
