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. Open access OMICS International Publishing Group aimed to provide the readers a barrier free flow of research work and conceptualized knowledge through online. To speed up the pace of scientific innovations, discovery, quality enriched education system and increase the global economy, open access is a key to success in dissemination of knowledge to world community. Bioenergetics: Open Access is one such open access journal from OMICS Group, publishing the research, review, case reports, short commentaries and editorials pertaining to the field of biochemistry, physiology, metabolism, energy related process in the living organisms and exercise physiology on quarterly basis for its readers. Today in the field of competition, quality of articles publishing in the journal per issue is very important with a rapid peer review process. Bioenergetics: Open Access journal trying to bring such quality in the articles published per issue with its broader conceptualized editorial board and with the expertise reviewers.
