myofibrils in English
In cross section, skeletal muscle fibers are seen to be composed of numerous small aggregates of contractile substance, the myofibrils .
Use "myofibrils" in a sentence
1. We tested whether phalloidin protects actin in myofibrils from depolymerization by ultraviolet light (UV).
2. The calcium sensitivity of ATPase activity of myofibrils and Actomyosins from insect flight and leg muscles
3. Chronic alterations in haemodynamic load or thyroid state affect the ATPase activity of myofibrils from the rat heart.
4. Ca2+ activate the ATP-ase of the myofibrils and of the actomyosin but not that of mitochondria (in presence of Mg2+).
5. Glycerinated rabbit psoas myofibrils, F-actin, and myofibril ghosts were irradiated with ultraviolet light (UV) to investigate how UV blocks myofibril contraction.
6. A significant decrease of Actomyosin, the contractile protein of the myofibrils was found in the rachitic rats in comparison to the healthy controls.
7. Actin definition is - a cellular protein found especially in microfilaments (such as those comprising myofibrils) and active in muscular contraction, cellular movement, and maintenance of cell shape
8. Obviously, the high degree of order of the myofibrils of vertebrate heart and skeletal muscle cells has developed from the loose and rapid changing arrangement of contractile filaments in ameboid cells.
9. Free energy is supplied to drive metabolic reactions, to transport molecules against concentration gradients (active transport), and to produce mechanical motion (contraction of myofibrils and microtubules), when Atp is hydrolyzed to
10. Sr2+ at concentrations about 30 times higher than Ca2+ was required for activating the ATPase of myofibrils or natural Actomyosins from fast skeletal, smooth and scallop striated muscles, while Sr2+ 8-13 times higher than Ca2+ was required for activating the slow skeletal or cardiac system.
11. Sr2+ at concentrations about 30 times higher than Ca2+ was required for activating the ATPase of myofibrils or natural Actomyosins from fast skeletal, smooth and scallop striated muscles, while Sr2+ 8-13 times higher than Ca2+ was required for activating the slow skeletal or cardiac system.
12. The low ATP-ase activity of isolated myosin and the superprecipitation of an actomyosin gel in the relaxing medium suggest that the relativly high ATP-ase of myofibrils and actomyosin gels is not a myosin ATP-ase but an actomyosin ATP-ase or an additional ATP-ase.
