biochemical change in muscle contraction
Answers
Explanation:
Action potential stimulates the sarcoplasmic reticulum to release calcium ions which initiate the biochemical changes in muscle contraction. Calcium and megnesium ions act as co-factors for myosine ATPase enzyme which hydrolyses ATP into ADP and inorganic phosphate releasing energy.
Biochemical Change in the muscle contraction ::
✴The impulse is sent from the nervous system to the muscle through the neuron.
✴The motor neuron carries impulses and The neurotransmitters are released in the neuromuscular junction.
✴These transmitters get bound to the cisterns of sarcoplasmic reticulum to release the calcium ions.
✴These calcium ions unmask the active site of the actin by causing conformational changes.
✴These leads to the binding of the Actin to myosin and leads to muscle contraction.
