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. Bioenergetics: Open Access is one of the best indexed journals in the field of biochemistry, physiology, metabolism, energy related process in the living organisms and exercise physiology, publishes the ongoing scientific research in the form of original research, review, case reports, editorials with the main focus on the quality of publishing. By the eminent personalities from the editorial and reviewer board, ensuring of the high quality and originality of the published content is achieved. OMICS Group International has been indexing all articles of Bioenergetics: Open Access to enhance visibility and credibility. It has a repertoire of over 700+ peer-reviewed journals of which, quality and originality are insured by 50,000+ editorial board members.
