Myosin is a contractile protein found in the muscles of animals as well as non-muscle cells. It is responsible for muscle contraction as well as intracellular transport. Myosin is made of six subunits including two heavy chains and four light chains. The molecule is considered to be made up of three … See more The contraction of skeletal muscles is responsible for all kinds of movements exhibited by animals. This contraction is possible due to the … See more Myosin is a protein that can be synthesized by almost all the cells in the process of gene expression. The genes for myosin molecules are present on different chromosomes, depending on the class of molecules. Some of … See more Myosin is a filamentous protein that belongs to the category of motor proteins. One myosin molecule is made up of six subunits. These … See more Myosin is a family of filamentous motor protein that is divided into different classes or groups. These classes differ concerning their structure, location of genes, and functions. Some of the major classes of myosin are … See more 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.

WebThe troponin-tropomyosin system is an important part of the A-level Biology curriculum. Students learn about the structure and function of these proteins, as well as their role in muscle contraction. They also learn about the regulation of muscle contraction and the potential consequences of problems with the troponin-tropomyosin system.
