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 journal is the best journal in the field of chemistry, physiology and metabolic related disorders of living organism’s inter-relation with the nature life cycle. It tries to bring the latest updates and ongoing current research all over the world in the field of bioenergetics to the aspirant and new readers to excel their skills and knowledge, useful in the institutional and carrier growth. Bioenergetics: Open Access provides the best review process with the two and more expertise reviewers from concerned field in 21 days and tries to publish the best quality of articles pertaining to the scope of the journal.
