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 the best peer-reviewed journals in relation to chemistry, physiology and metabolic related disorders of living organisms with the nature life cycle scope journals from OMICS International publishing group. Articles published in this peer-reviewed journal have a rapid peer review process and are reviewed by at least two reviewers form the related expertise fields. Two comments like major and minor is followed for quality of the articles and final decision rests on the editor for the respective articles from editorial board of the journal. Bioenergetics: Open Access peer review journals covers the broader scopes stressing on the topics of biochemistry, physiology, metabolism, energy related process in the living organisms and exercise physiology including but not limited to the above discussed fields. OMICS Group is one of the best international publishers with 700+ peer-reviewed journals along with eminent scientists in its Editorial Board and expert reviewers to carry rigorous peer-review process. The peer review process is highly appreciated by researchers globally. In addition to peer review open-access publishing, OMICS also provides E-books, Scholar Central and more than 3000+ International Scientific Conferences under its umbrella.
