Homework Answers
Answer:
76. True
G actin is a globular protein which polymerises to form F actin which are long filaments. The polymerization takes place by ATP.
77. False.
Thin filaments are composed of actin. They also contain Troponin and tropomyosin.
78. False.
Each Thick filaments consists of about 250 myosin molecules.
79. False
The power stroke is generated during contraction phase.
