The central force-generating element that the two types of motor proteins (Kinesin and Myosin) have in common includes the site of ATP binding and the machinery necessary to translate ATP hydrolysis into an allosteric conformational change. Kinesin must use the energy derived from ATP binding and hydrolysis to force a large movement in part of the protein molecule. When kinesin forms a rigor-like tight association with the head location of the microtubule, the ATP is bound to the kinesin, and it is hydrolysis of ATP that promotes release of the motor from its track. Thus, myosins can typically drive filament sliding much more rapidly than kinesins, even though they hydrolyze ATP at comparable rates and take molecular steps of comparable length.
Cnidarians were the first phylum that scientists saw tissue level organization in. Tissue level organization meaning cells all of one type start to function in a unified way.
