ATubulin
BKeratin
CMyosin
DDynein
Answer & Solution
Correct answer: C. Myosin
1. Actin is powered by ATP to assemble into its filamentous form.
2. That filament serves as a track for a motor protein.
3. The motor protein named is myosin.
4. Actin and myosin are plentiful in muscle cells, and their sliding past each other contracts the muscle.
5. The motor protein is myosin.
