Motor proteins, fueled by ____, move cellular cargo along tracks of ____.

A) sugars; intermediate filaments and microtubules
B) ATP; microtubules and microfilaments
C) ATP; intermediate filaments and cilia
D) sugars; intermediate filaments and microfilaments
E) triglycerides; microtubules and microfilaments

Motor Proteins

Proteins that convert chemical energy into mechanical work, driving cellular movements such as muscle contraction and intracellular cargo transport.

Intermediate Filaments

A component of the cell cytoskeleton, providing mechanical support for cells and tissues and involved in cell adhesion, transport, and integrity.

Microtubules

Cylindrical structures within the cell that are part of the cytoskeleton, involved in maintaining cell shape, division, and intracellular transport.
