Perhaps the most fascinating proteins that associate with the cytoskeleton are the molecular motors called motor proteins. These remarkable proteins bind to a polarized cytoskeletal filament and use the energy derived from repeated cycles of ATP hydrolysis to move steadily along it. Dozens of different motor proteins coexist in every eucaryotic ...

neurones. They are adapted to carry electrical impulses from one place to another. A bundle of neurones is called a nerve. There are three main types of neurone: sensory, motor and relay. They...
Mar 1, 2000 · Molecular motors are responsible for almost all biologically interesting motion. They support efficient, sustained, directional motility of cellular components within cells, of entire cells over surfaces and of entire organisms. Motors allow cells to set up complex structure, and then continuously to maintain and adjust it, by directing packets ...
Jan 8, 2020 · In biological systems, molecular motors made of proteins and nucleic acids are ubiquitous, and commonly use the chemical energy of ATP or the electrochemical potential of protons across the cell membrane (the so-called proton-motive force) as an energy source.
