Sometimes cytoplasm acts like a watery solution, and sometimes it takes on a more gel-like consistency. A framework of protein scaffolds called the cytoskeleton provides the cytoplasm and the cell with structure.

Skeleton muscle tissue is composed of sarcomeres, the functional units of muscle tissue. Muscle contraction occurs when sarcomeres shorten, as thick and thin filaments slide past each other, which is called the sliding filament model of muscle contraction. ATP provides the energy for cross-bridge formation and filament sliding.

These strands are made up of small globular actin (g-actin) subunits that stack on one another with relatively small points of contact.

It covers the actomyosin cross-bridge cycle, the interaction of actin and myosin, and the regulation of muscle contraction through proteins like troponin and tropomyosin, with a detailed explanation of the biochemical underpinnings of these processes.

These operate at the cellular and organismal level and are known as motor proteins. Motor proteins rely on globular structural proteins, so it is important that we describe how these cellular “railways” are assembled before discussing the motor proteins themselves. There are two relevant fibrous structures serving as rails for motor proteins.
