Final Answer:
The class of cytoskeletal filaments that has a monomer binding to ATP is actin filaments.
Step-by-step explanation:
Actin filaments are a crucial component of the cytoskeleton, providing structural support to the cell and playing a key role in various cellular processes such as cell motility and division. The monomer of actin, called G-actin (globular actin), binds to ATP. G-actin molecules polymerize to form long, filamentous structures known as F-actin (filamentous actin).
The energy derived from ATP hydrolysis during polymerization and depolymerization processes helps drive the dynamic nature of actin filaments, allowing cells to undergo shape changes, migration, and other essential functions. The binding and hydrolysis of ATP by actin monomers contribute to the regulation and versatility of actin filament dynamics.
