OMICS International organises 3000+ Global Conferenceseries Events every year across USA, Europe & Asia with support from 1000 more scientific societies and Publishes 700+ Open Access Journals which contains over 50000 eminent personalities, reputed scientists as editorial board members.

Muscle Contraction

The term Muscle contraction is defined as the stretching or relaxation of the muscle fibers. There are two kinds of Muscle contraction named voluntary and involuntary. Voluntary muscle contraction is controlled by the central nervous system. Involuntary muscle contraction is controlled by the innate or involuntary brain activity or stimuli. Two important proteins actin and myosin play vital role in the energy dependent function of the muscle. Action potential originating in CNS by calcium signaling releases acetylcholine this in turn drives the actin, myosin functions by ATP. Calcium binds to TroponinC present on the actin making it to unblocking the binding sites. Myosin binds to the unblocked binding sites on the thin filament of actin. The conversion of ADP to ATP results in the power stroke. Actin acts as a cofactor advancing the release. This results in dragging the Z-bands towards each other and shortening the I-band. Repetition of these cycles results in muscle contraction or release. OMICS Group an open access publishing is one among the top open access publishing group internationally. OMICS Group succeeded in reaching top position with its 700+ peer-reviewed journals and conducting more than 3000+ International Scientific Conferences worldwide annually. Marking its identity in the top open access journals and improvising itself in the quality and newness in the world of science. Bioenergetics: Open Access is one such journal from OMICS Group, made its way to be top in journals related to biochemistry, physiology, metabolism, energy related process in the living organisms and exercise physiology related journals globally.
