Question

question 1 1 pts a motor protein: \walks\ along a cytoskeletal fiber \wheels\ along a cytoskeletal fiber question 2 1 pts microtubules disassemble from the _____ end. plus minus question 3 1 pts myosin binds to: microtubules actin filaments

Explanation:

• Question 1: Motor proteins move along cytoskeletal fibers through a 'walking' - like mechanism by using energy from ATP hydrolysis to change their conformation and move step - by - step.
• Question 2: Microtubules have polarity, and disassembly often occurs from the minus end.
• Question 3: Myosin is a motor protein that binds to actin filaments during muscle contraction and other cellular motility processes.

Answer:

Question 1: "walks" along a cytoskeletal fiber
Question 2: minus
Question 3: actin filaments
