MUSCLE PHYSIOLOGY

Detailed explanation-1: -Actin is the most abundant protein in most eukaryotic cells. It is highly conserved and participates in more protein-protein interactions than any known protein.

Detailed explanation-2: -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-3: -Actin is a highly abundant intracellular protein present in all eukaryotic cells and has a pivotal role in muscle contraction as well as in cell movements. Actin also has an essential function in maintaining and controlling cell shape and architecture.
