Which Functions as a Motor Protein in All Three Types

Question

Which functions as a motor protein in all three types of muscle tissue?
A)actin
B)myosin
C)troponin
D)titin
E)tropomyosin

Accepted Answer

Myosin is a motor protein that plays a central role in the contraction of all three types of muscle tissue. It works by binding to actin filaments and using energy from ATP to generate force and movement. The other choices (A, C, D, and E) are involved in muscle contraction but do not function as a motor protein.
