WebThe actin doesn't produce energy, it is like a long fibre. The myosin uses energy to produce force. One myosin molecule with two heads produces about 1.4 picoNewtons (0.0000000000014 Newtons) of force when it changes conformation. Actin and myosin form fibres that are across the whole length of the muscle cell.

WebMyosin cannot be placed into either of the two groups since it consists of a fibrous "tail" and a globular "head". The globular part of myosin binds actin and binds and hydrolyses ATP. The energy from ATP is then used in the sliding filament mechanism. Myosin and actin are motor proteins, which hydrolysis ATP to use the energy to move along ... WebProteins are usually put into two different groups according to their structural appearance – fibrous proteins and globular proteins.

Webmyosin: [noun] a fibrous globulin of muscle that can split ATP and that reacts with actin in muscle contraction to form actomyosin. WebThe motion of muscle shortening occurs as myosin heads bind to actin and pull the actin inwards. This action requires energy, which is provided by ATP.

WebFibrous proteins are structural in nature, which means they help maintain cell shape by providing a scaffolding or a framework. On the other hand, globular proteins are functional, which means they carry out a specific biological function in the body.
