BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Actin filaments, usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor-a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.

Detailed explanation-2: -The Structure of Muscles The cytoplasm of muscle fibers contains long, thread-like structures called myofibrils, which are made up of bundles of thick, myosin filaments and thin actin filaments.

Detailed explanation-3: -Myofibrillar Proteins: Muscle fibers are composed of myofibrils. The proteins that comprise the myofibril, including actin and myosin and several more. The myofibrillar protein components most important for muscle fiber structure are actin and myosin.

Detailed explanation-4: -Actin and myosin are found in almost all eukaryotic cells and are required for diverse cellular functions, including muscle contraction, cell motility, cell adhesion, cytokinesis, and organelle transport (1).
