The sliding protein of muscle:
Correct answer: C. Myosin
- A. Tubulin
- B. Myoglobin
- C. Myosin
- D. Actin
Explanation
Myosin is the sliding protein of muscle and is primarily responsible for generating force and producing muscle contractions. Myosin is a motor protein that interacts with actin, another protein, to generate muscle contraction. Myosin consists of two twisted polypeptide chains, with globular heads that form cross-bridges with actin filaments. These cross-bridges undergo a cyclic interaction, resulting in the sliding of actin filaments along myosin filaments, leading to muscle contraction.

About Support and Movement
Support and movement covers the axial and appendicular skeleton, bone structure, joints and the arrangement of skeletal muscles. Muscle contraction is explained through actin, myosin, sliding filaments, calcium ions and ATP, while arthritis is distinguished as a disorder of joints rather than a normal part of movement.
